1) Dynamic geological processes within the Earth continually recycle rocks and form mineral deposits while also causing volcanic eruptions, earthquakes, and tsunamis.
2) The available supply of a nonrenewable mineral resource depends on its quantity in the Earth's crust, the rate of usage, mining technology, market prices, and the environmental impacts of extraction and use. As resources become scarcer, negative environmental effects tend to increase.
3) More sustainable use of minerals involves finding substitutes, reducing waste, and increasing reuse and recycling to extend supplies while lowering environmental impacts.
The document discusses geology and nonrenewable mineral resources. It describes the dynamic geological processes involved in the rock cycle and plate tectonics. These processes form mineral deposits but can also cause natural hazards like earthquakes and tsunamis. It also addresses how the available supply of mineral resources depends on usage rates and mining impacts. Finally, it suggests more sustainable approaches like reducing waste, finding substitutes, and increasing reuse and recycling of scarce nonrenewable minerals.
This document discusses nonrenewable mineral resources and geology. It describes how tectonic plates interact at divergent, convergent, and transform boundaries, causing volcanoes, earthquakes, and tsunamis. Mining has harmful environmental effects like pollution, waste, and land disruption. Supply of minerals depends on reserves, usage rate, and effects of extraction and use. More sustainable practices include reducing waste, recycling, and substituting scarce resources.
The process of obtaining mineral resources from the Earth involves extracting resources through various mining methods. Surface mining techniques include open pit mining, strip mining, quarrying, and solar evaporation. Subsurface techniques include room-and-pillar mining, longwall mining, and solution mining. Mining provides resources for energy, technology, infrastructure, and more, but can negatively impact the environment through air and water pollution, wildlife displacement, erosion, and other issues. Regulations aim to reduce environmental impacts and require reclamation of mined lands.
The document discusses minerals and their extraction from Earth. It begins by explaining how the planet formed and developed a rocky crust rich in minerals. It then examines various types of minerals and rocks, as well as how minerals are vital resources. However, mineral extraction causes significant environmental impacts. Creating a sustainable mineral production system requires conservation, recycling, restoration, and expanding reserves through new technologies.
This document discusses minerals, their economic importance, depletion, and the need for conservation. It notes that minerals are essential resources but non-renewable, as their formation occurs over millions of years. While minerals provide the base for industry and jobs, the large-scale exploitation since the Industrial Revolution has resulted in decreasing supplies and increasing demand. Conservation efforts are needed to use minerals sustainably and reduce waste so they can last for future generations.

Mining and mineral processing (mining of silverSaid Al-Qurri
Mining is the extraction of valuable minerals and materials from the earth. It involves prospecting for ore bodies, extracting the desired materials, and reclaiming the land after. Common ores extracted include metals, coal, gemstones, and more. While mining provides important resources, it often creates environmental and safety issues. As such, regulations aim to reduce impacts. Recycling rates of metals are generally low as well. The exploration process for minerals varies by site and material, with the goal being to discover economically feasible deposits to develop into mines.
This document summarizes information about mineral resources, including their classification, uses, exploitation, and conservation. It defines a mineral as a naturally occurring inorganic substance with a defined chemical composition and crystal structure. Minerals are classified as metallic or non-metallic, and energy minerals are those used to generate energy like coal. Extraction methods are surface mining and subsurface mining. While mineral resources are important for development, their exploitation can cause environmental problems and depletion of high-grade minerals if not managed sustainably. Conservation efforts include protecting deposits, improving recovery efficiency, reuse, and using alternatives.
Mining is the extraction of valuable materials from the earth. It is required to obtain materials that cannot be grown or made artificially. There are several types of mining including surface mining methods like open pit and strip mining, and subsurface mining methods like shaft, slope, and drift mining. Mining is important economically but can also cause environmental damage and health issues for miners. Key issues include mine safety, pollution from mine tailings and acid mine drainage, and damage to landscapes and water bodies. Regulations aim to reduce risks but mining continues to impact communities and environments.
Mining is the extraction of valuable minerals and materials from the earth. There are two main types of mining: surface mining, which takes place above ground, and subsurface mining, which occurs underground. Surface mining techniques include open-pit and strip mining and can cause significant environmental damage through habitat destruction and pollution. Subsurface mining techniques include shaft, slope, and drift mining and can be dangerous for miners due to risks of collapse, fire, and exposure to harmful substances. All mining operations generate waste materials that must be properly managed to prevent pollution of air and water if reclamation efforts are to be successful.

Environmental threats and reclamation after underground mining 1Tharindu Dilshan
Underground gem mining in Sri Lanka provides economic and social benefits but also poses significant environmental threats if not properly managed. Traditional pit mining damages water and soil quality, destroys habitats, and endangers humans. Effective mine reclamation, including stabilizing land, restoring vegetation and water flows, and closing pits, is needed to mitigate long-term environmental impacts and allow the pre-mining land use to resume after mining ceases. While gem mining provides livelihoods, greater regulation and enforcement is required to minimize damage to the environment.
1. The document discusses different types of mining including surface mining techniques like placer mining, strip mining, mountaintop removal, and hydraulic mining. It also discusses underground mining techniques like drift mining, slope mining, and shaft mining.
2. Mining can have negative environmental impacts like deforestation, pollution from tailings dams, subsidence from underground coal mining, and dispersal of heavy metals and asbestos.
3. Mining also causes social damages like appropriation of indigenous lands, health impacts, changes to social relationships and regional cultures, and displacement of local communities and economies. The case study of Sukinda valley in India shows large negative health impacts from chromite mining pollution.
Ore minerals are found through geological studies and testing of soil and rocks. They are mined through surface or underground mining methods then processed. Processing involves sampling, analysis, crushing, separating minerals from waste through techniques like gravity or magnetic separation, and dewatering the concentrates. Fossil fuels like coal, oil and gas were formed from the remains of ancient organisms buried underground. Coal formed from decayed plants, while oil and gas formed from marine organisms. They are non-renewable and contribute to environmental issues when burned.
This document discusses coal mining practices and their environmental impacts. It begins by explaining that coal and other minerals are mined to produce energy and materials like steel. Several mining techniques are described, including surface mining methods like mountaintop removal and subsurface techniques like longwall mining. The document notes that while mining is important, it can cause issues like water and air pollution, subsidence, and damage to landscapes. Laws like the Surface Mining Control and Reclamation Act were passed to regulate impacts and require cleanup, but mining continues to significantly alter environments.
4 mining and its impacts to environmentanonymous143
- Mining involves extracting valuable minerals from the earth through various surface and underground methods. Surface methods include strip mining, open-pit mining, mountaintop removal, and dredging. Underground methods involve excavating tunnels and shafts.
- The extraction process produces both ore and waste rock. Ore undergoes crushing, grinding, and separation processes like flotation and cyanidation to extract minerals.
- Mining has environmental impacts like flooding, erosion, water and air pollution, and wildlife habitat damage. Preventive measures include replanting vegetation and stabilizing slopes. The government regulates mining through agencies like MGB and EMB and laws like the Mining Act.
This document discusses mining methods, their environmental and social impacts, and efforts to restore mined lands. It describes how minerals are extracted through various mining techniques like strip mining, underground mining, open pit mining and mountaintop removal. These methods can significantly damage the environment by destroying habitats, polluting water sources, and degrading land. The document also notes issues like human rights abuses during mineral extraction in places like the Democratic Republic of Congo and challenges with fully restoring mined lands.
Mining and mineral extraction can have harmful environmental effects. Surface mining disrupts land and leaves exposed pits, while underground mining is dangerous. Mining produces acid mine drainage when exposed sulfur reacts with water and oxygen to form acid, polluting nearby streams. Heavy metals from excavated rock can also leach into water sources. Chemicals used to process ores, like cyanide and sulfuric acid, can spill and contaminate water if not properly contained. Large amounts of erosion and sedimentation from disturbed earth further degrades water quality and smothers aquatic life. Proper reclamation, containment, and pollution prevention are needed to reduce mining's environmental impacts.
This document discusses nonrenewable mineral resources and the environmental impacts of mining. It defines minerals, ores, and gangue and describes the distribution of abundant and scarce metals. Mining activities can release acid mine drainage and heavy metal contamination into water sources from ore exposure. Processing chemicals and erosion from mining also pollute the environment. While recycling and new exploration methods help meet demand, mineral supply concerns remain for some resources due to increasing global consumption. The document examines specific health impacts of four persistent, bioaccumulative metals - lead, mercury, cadmium, and arsenic - which are released from mining and fossil fuel combustion. Regulations aim to reduce risks to humans and wildlife from exposure to these toxic heavy metals.
The document provides information about fossil fuels, including coal, oil, and natural gas. It discusses how each fossil fuel is formed over millions of years from the remains of ancient plants and animals. Coal forms in swampy environments as plants are buried and subjected to heat and pressure over time. Oil forms from the remains of plankton and other tiny organisms buried in sedimentary rock layers. Both coal and oil require heat, pressure, and the absence of oxygen to form from biological material into usable fossil fuels over millions of years. The document also notes some of the key uses of coal and oil as fuel sources.
This document summarizes information about nonrenewable mineral resources and the impacts of mining. It discusses how minerals and metals are distributed unevenly around the world, and how mining activities can release toxic and acid drainage that pollutes waterways. Mining processes like crushing ores and smelting can also spread pollutants. The document focuses on four metals (lead, mercury, cadmium, and arsenic) that are especially persistent, bioaccumulative and toxic, explaining their health effects and major sources like coal burning.
This document provides information about various aspects of mineral resources and mining. It discusses three current boom employers for geologists: mineral resources and mining, the petroleum industry, and the environmental industry.

Why Psychological Safety Matters for Software Teams - ACE 2024 - Ben Linders.pdfBen Linders
Psychological safety in teams is important; team members must feel safe and able to communicate and collaborate effectively to deliver value. It’s also necessary to build long-lasting teams since things will happen and relationships will be strained.
But, how safe is a team? How can we determine if there are any factors that make the team unsafe or have an impact on the team’s culture?
In this mini-workshop, we’ll play games for psychological safety and team culture utilizing a deck of coaching cards, The Psychological Safety Cards. We will learn how to use gamification to gain a better understanding of what’s going on in teams. Individuals share what they have learned from working in teams, what has impacted the team’s safety and culture, and what has led to positive change.
Different game formats will be played in groups in parallel. Examples are an ice-breaker to get people talking about psychological safety, a constellation where people take positions about aspects of psychological safety in their team or organization, and collaborative card games where people work together to create an environment that fosters psychological safety.

Suzanne Lagerweij - Influence Without Power - Why Empathy is Your Best Friend...Suzanne Lagerweij
This is a workshop about communication and collaboration. We will experience how we can analyze the reasons for resistance to change (exercise 1) and practice how to improve our conversation style and be more in control and effective in the way we communicate (exercise 2).
This session will use Dave Gray’s Empathy Mapping, Argyris’ Ladder of Inference and The Four Rs from Agile Conversations (Squirrel and Fredrick).
Abstract:
Let’s talk about powerful conversations! We all know how to lead a constructive conversation, right? Then why is it so difficult to have those conversations with people at work, especially those in powerful positions that show resistance to change?
Learning to control and direct conversations takes understanding and practice.
We can combine our innate empathy with our analytical skills to gain a deeper understanding of complex situations at work. Join this session to learn how to prepare for difficult conversations and how to improve our agile conversations in order to be more influential without power. We will use Dave Gray’s Empathy Mapping, Argyris’ Ladder of Inference and The Four Rs from Agile Conversations (Squirrel and Fredrick).
In the session you will experience how preparing and reflecting on your conversation can help you be more influential at work. You will learn how to communicate more effectively with the people needed to achieve positive change. You will leave with a self-revised version of a difficult conversation and a practical model to use when you get back to work.
Come learn more on how to become a real influencer!

23. 14-2 How Are the Earth’s Rocks Recycled?
• Concept 14-2 The three major types of rocks found
in the earth’s crust—sedimentary, igneous, and
metamorphic—are recycled very slowly by the
process of erosion, melting, and metamorphism.
24. There Are Three Major Types of Rocks (1)
• Minerals

29. 14-3 What Are Mineral Resources, and
What Are their Environmental Effects?
• Concept 14-3 We can make some minerals in the
earth’s crust into useful products, but extracting and
using these resources can disturb the land, erode
soils, produce large amounts of solid waste, and
pollute the air, water, and soil.
30. We Use a Variety of Nonrenewable
Mineral Resources (1)
• Mineral resource
• Can be extracted from earth’s crust and processed into raw
materials and products at an affordable cost
• Metallic minerals
• Nonmetallic minerals
• Ore
• Contains profitable concentration of a mineral
• High-grade ore
• Low-grade ore
31. We Use a Variety of Nonrenewable
Mineral Resources (2)
• Metallic mineral resources
• Aluminum
• Iron for steel
• Copper
• Nonmetallic mineral resources
• Sand, gravel, limestone
• Reserves: estimated supply of a mineral resource
32. Some Environmental Impacts of Mineral
Use
• Advantages of the processes of mining and
converting minerals into useful products
• Disadvantages
35. There Are Several Ways to Remove
Mineral Deposits (1)
• Surface mining
• Shallow deposits removed

• Spoils: waste material
• Subsurface mining
• Deep deposits removed
36. There Are Several Ways to Remove

47. 14-4 How Long Will Supplies of Nonrenewable
Mineral Resources Last?
• Concept 14-4A All nonrenewable mineral resources
exist in finite amounts, and as we get closer to
depleting any mineral resource, the environmental
impacts of extracting it generally become more
harmful.
• Concept 14-4B Raising the price of a scarce mineral
resource can lead to an increase in its supply, but
there are environmental limits to this effect.
48. Mineral Resources Are Distributed
Unevenly (1)
• Most of the nonrenewable mineral resources
supplied by
• United States
• Canada
• Russia
• South Africa
• Australia
• Sharp rise in per capita use in the U.S.
49. Mineral Resources Are Distributed
Unevenly (2)
• Strategic metal resources
• Manganese (Mn)
• Cobalt (Co)
• Chromium (Cr)
• Platinum (Pt)
50. Supplies of Nonrenewable Mineral Resources
Can Be Economically Depleted
• Future supply depends on
• Actual or potential supply of the mineral
• Rate at which it is used
• When it becomes economically depleted
• Recycle or reuse existing supplies
• Waste less
• Use less
• Find a substitute
• Do without
• Depletion time: time to use a certain portion of reserves
52. Market Prices Affect Supplies of
Nonrenewable Minerals
• Subsidies and tax breaks to mining companies keep
mineral prices artificially low
• Does this promote economic growth and national
security?
• Scarce investment capital hinders the development
of new supplies of mineral resources
53. Case Study: The U.S. General Mining
Law of 1872
• Encouraged mineral exploration and mining of hard-
rock minerals on U.S. public lands
• Developed to encourage settling the West (1800s)
• Until 1995, land could be bought for 1872 prices
• Companies must now pay for clean-up
55. Is Mining Lower-Grade Ores the Answer?
• Factors that limit the mining of lower-grade ores
• Increased cost of mining and processing larger
volumes of ore
• Availability of freshwater
• Environmental impact

• Use microorganisms, in situ
• Slow process
• What about genetic engineering of the microbes?
56. Can We Extend Supplies by Getting More
Minerals from the Ocean?
• Mineral resources dissolved in the ocean -- low
concentrations
• Deposits of minerals in sediments along the shallow
continental shelf and near shorelines
• Hydrothermal ore deposits
• Metals from the ocean floor: manganese nodules
• Effect of mining on aquatic life
• Environmental impact
58. 14-5 How Can We Use Mineral Resources
More Sustainability?
• Concept 14-5 We can try to find substitutes for
scarce resources, reduce resource waste, and recycle
and reuse minerals.
59. We Can Find Substitutes for Some Scarce
Mineral Resources
• Materials revolution
• Nanotechnology
• Ceramics
• High-strength plastics
• Drawbacks?
• Substitution is not a cure-all
• Pt: industrial catalyst
• Cr: essential ingredient of stainless steel
60. Science Focus: The Nanotechnology
Revolution

• Uses
• Nanoparticles
• Are they safe?
• Investigate potential ecological, economic, health, and
societal risks
• Develop guidelines for their use until more is known about
them
61. We Can Recycle and Reuse
Valuable Metals
• Recycling
• Lower environmental impact than mining and
processing metals from ores
• Reuse
63. We Can Use Mineral Resources More
Sustainability
• How can we decrease our use and waste of mineral
resources?
• Pollution and waste prevention programs
65. Case Study: Pollution Prevention Pays
• Begun in 1975 by 3M company, a very large
manufacturing company
• Redesigned equipment and processes
• Fewer hazardous chemicals
• Recycled or sold toxic chemical outputs
• Began making nonpolluting products
• Company saved $1.2 billion
• Sparked cleaner production movement
66. Three Big Ideas
1. Dynamic forces that move matter within the earth
and on its surface recycle the earth’s rocks, form
deposits of mineral resources, and cause volcanic
eruptions, earthquakes, and tsunamis.
2. The available supply of a mineral resource depends
on how much of it is in the earth’s crust, how fast
we use it, mining technology, market prices, and
the harmful environmental effects of removing and
using it.
67. Three Big Ideas
3. We can use mineral resources more sustainably by
trying to find substitutes for scarce resources,
reducing resource waste, and reusing and recycling
nonrenewable minerals.
Editor's Notes
Figure 14.1: This gold mine in the Black Hills of the U.S. state of South Dakota has disturbed a large area of land. This site also contains cyanide leach piles and settling ponds that are highly toxic to wildlife in the immediate area.
Figure 14.2: The earth’s crust and upper mantle have certain major features. The lithosphere, composed of the crust and outermost mantle, is rigid and brittle. The asthenosphere, a zone in the mantle, can be deformed by heat and pressure.
Figure 14.3: The earth’s crust is made up of a mosaic of huge rigid plates, called tectonic plates, which move very slowly across the asthenosphere in response to forces in the mantle. See an animation based on this figure at CengageNOW.
Figure 14.4: This map shows the earth’s major tectonic plates. See an animation based on this figure at CengageNOW. Question: Which plate are you riding on?
Figure 14.5: This is the San Andreas Fault as it crosses part of the Carrizo plain between San Francisco and Los Angeles, California (USA). This fault, which runs almost the full length of California, is responsible for earthquakes of various magnitudes. Question: Is there a transform fault near where you live?
Figure 14.6: A volcano is created when magma in the partially molten asthenosphere rises in a plume through the lithosphere to erupt on the surface as lava (photo inset), which builds into a cone. Sometimes, internal pressure is high enough to cause lava, ash, and gases to be ejected into the atmosphere or to flow over land, causing considerable damage. Some volcanoes that have erupted and then become inactive have formed islands or chains of islands.
Figure 14.7: An earthquake (left), one of nature’s most powerful events, has certain major features and effects. In 2010, a major 7.0 earthquake in Haiti (right) killed at least 72,000 people and devastated this already very poor country.
Figure 14.7: An earthquake (left), one of nature’s most powerful events, has certain major features and effects. In 2010, a major 7.0 earthquake in Haiti (right) killed at least 72,000 people and devastated this already very poor country.
Figure 14.8: This diagram illustrates how a tsunami forms. The map shows the area affected by a large tsunami in December 2004.
Figure 14.9: In December 2004, a great earthquake with a magnitude of 9.15 on the seafloor of the Indian Ocean generated a tsunami that killed 168,000 people in Indonesia, as well as tens of thousands more in other countries bordering the Indian Ocean. These photos show the Banda Aceh Shore near Gleebruk in Indonesia on June 23, 2004 before the tsunami (left), and on December 28, 2004 after it was stuck by the tsunami (right).
Figure 14.10: Natural capital.
The rock cycle is the slowest of the earth’s cyclic processes. Rocks are recycled over millions of years by three processes: erosion, melting, and metamorphism, which produce sedimentary, igneous, and metamorphic rocks. Rock from any of these classes can be converted to rock of either of the other two classes or can be recycled within its own class (Concept 14-2). Question: What are three ways in which the rock cycle benefits your lifestyle?
Figure 14.11: Each metal resource that we use has a life cycle. Each step in this process uses large amounts of energy and water, and produces some pollution and waste.
Figure 14.12: The extraction, processing, and use of any nonrenewable mineral or energy resource all contribute to a number of harmful environmental effects (Concept 14-3). Further, providing the energy required to carry out each step causes additional pollution and environmental degradation. Questions: What are three mineral resources that you used today? Which of these harmful environmental effects might have resulted from obtaining and using these resources?
Figure 14.13: Natural capital degradation.
This open-pit copper mine, which is located near the U.S. city of Bisbee, Arizona, has been abandoned since the mid-1970s. Question: Should governments require mining companies to fill in and restore such sites once their ore is depleted? Explain.
Figure 14.14: This heavy piece of equipment with a large bucket is removing material from an area-strip-mining operation in the U.S. state of Wyoming.
Figure 14.15: Natural capital degradation.
Contour strip mining is used in hilly or mountainous terrain to extract minerals such as coal.
Figure 14.16: Natural capital degradation.
Area strip mining of coal in Germany created these spoils banks. A coal-burning power plant is in the background. Question: Should governments require mining companies to restore such sites as fully as possible? Explain.
Figure 14.17: Natural capital degradation.
This is a mountaintop coal mining operation in the U.S. state of West Virginia, where coal is the state rock. The large amount of debris that results from this method is deposited in the valleys and streams below. Mountaintop removal for coal is also occurring in the U.S. states of Virginia, Tennessee, Kentucky, and Pennsylvania. See other sites at http://www.appvoices.org/. Question: Are you for or against mountaintop coal mining? Explain.
Figure 14.18: This mining site in Indonesia has been ecologically restored, but such restoration is rare.
Figure 14.19: Natural capital depletion.
Each of these depletion curves for a nonrenewable resource (such as aluminum or copper) is based on a different set of assumptions. Dashed vertical lines represent the times at which 80% depletion occurs.
Figure 14.20: Natural capital degradation.
This Summitville gold mining site near Alamosa, Colorado, became a toxic waste site after the Canadian company that owned it declared bankruptcy and abandoned it, rather than cleaning up the acids and toxic metals that leaked from the site into the nearby Alamosa River. Cleanup by the EPA will cost U.S. taxpayers about $120 million.
Figure 14.21: Natural capital.
Hydrothermal deposits form when mineral-rich superheated water shoots out of vents in solidified magma on the ocean floor near some tectonic plate boundaries. As this water mixes with cold seawater, black particles of metal sulfides precipitate out and build up as chimney-like mineral deposits around the vents. A variety of rare and exotic forms of life—including giant clams, six-foot tubeworms, and eyeless shrimp—exist in the dark depths around these black smokers. These life-forms are supported by bacteria that produce food through chemosynthesis from sulfur compounds discharged by the vents.
Figure 14.22: These compacted bales of aluminum cans are ready for recycling. About 54% of the aluminum cans used in the United States are recycled.
Figure 14.23: We can use nonrenewable mineral resources more sustainably (Concept 14-5). Questions: Which two of these solutions do you think are the most important? Why?
