This document discusses mineral resources and mining. It begins by defining mineral resources and providing an overview of India's national mineral scenario. It then lists some of the major metal reserves around the world and their common uses. The document estimates the life expectancies of various mineral resources based on reserve size and usage rates. It also outlines where in India certain key minerals like iron, coal, copper, etc. are located. The effects of different types of mining like surface and underground on the environment are discussed. The document concludes with a case study on mining and its impacts in Udaipur, India.

2. Mineral Resource is defined as a
occurrence of natural, solid, inorganic
or fossilized organic material in or on
the Earth’s crust in such form and
quantity and of such a grade or quality
that it has reasonable prospects for
economic extraction.

3. National Mineral Scenario
India produces as many as 87 minerals,
which includes 4 fuel, 10 metallic, 47 non-
metallic, 3 atomic and 23 minor minerals
(including building and other materials).
• India possesses a large variety of
mineral-ores in fairly huge quantities.
• India is rich in coal, manganese, iron,
chromites and mica. It is deficient in the
gold, silver, nickel etc.

4. Major Reserve and important uses
Metal Major World Resources Major uses
Aluminium Australia, Guinea, Jamaica Packaging food items, transportations, utensils
Chromium CIS, South Africa For making high strength steel alloys
Copper USA, Canada, CIS, Chile, Zambia Electric and Electronic goods
Iron CIS, South America, Canada, USA Heavy machinery, steel production transportation means
Lead North America, USA,CIS Leaded gasoline,Car batteries, paints
Manganese South Africa, CIS, Brazil, Gabon High strength, heat resistant steel alloys
Platinum group South Africa , CIS Use in Automobiles, catalytic converters, electronics, medical uses
Gold South Africa ,CIS, Canada Ornaments, medical use, electronics use
Silver Canada, South Africa, Mexico Photography, electronics, jeweler
Nickel CIS, Canada, New CaledoniaJuly 22, 2012 Footer text here4

5. Estimated life expiry of minerals depends on two things:
1. the size of the reserve
2. the rate at which we are using it up!
Resource Est. Life Exp. in Yrs. Uses
• Coal 200-300 (electricity)
• Copper 36 (electric wiring)
• Iron 62 (steel prod.)
• Lead 25 (batteries)
• Natural Gas 125 (fuel; heat)
• Oil 50 (gasoline)
• Silver 17 (electric wiring)
• Tin 31 (cans; industry)
• Uranium ??? (electricity)

33. Surface mines are mining operations that delve into rock to
extract deposits of mineral resources that are close to the
surface .
In most forms of surface mining, heavy equipment, such as
earthmovers, first remove the overburden (the soil and rock
above the deposit). Next, huge machines such as drag line
excavators extract the mineral.
Once the material has been removed, the land is
recovered for safe use on the surface through a process called
reclamation.
Surface Mining

35. Some effects of mining on the
environment
•Deforestation and loss of biodiversity are
major effects of mining.(It destroys forest and
wetlands. It may mean that you have to cut down lots of
trees just to get to the spot that has all the gold or
iron ore).
•Many mine require tailings dams to prevent waste being
washed into the rivers. Unethical miners can dispense
with the dams, to save costs, resulting in massive
pollution downstream. In other cases, the tailings dam
can overflow, and even breach, during periods of heavy
rain.

37. •Underground coal mining can require the removal of
almost an entire layer of material deep under the
surface. When the timber supports collapse, this can
lead to subsidence. The subsidence can mean economic
loss to people above or damage to natural areas. It can
even cause cracks in river beds, leading to loss of river
flow.

39. •Some mining involves the inadvertent dispersal of
heavy metals, such as lead, into the atmosphere. This
can have serious health effects, including mental
retardation in children.
•Asbestos mining causes the dispersal of asbestos
into the environment. This will cause deaths among
local residents and workers, often several decades
later. Fortunately, the mining and use of asbestos are
banned in most parts of the world.

41. Because these mineral resources are nonrenewable,
we must plan for a day when they will disappear.
-What can we do?
1. find alternative resources
2. develop efficient and reliable renewable resources
3. reduce our use and avoid waste
4. reuse what we can
5. recycle (collect and reuse materials from waste)
what we can
Examples: hybrid/electric cars, carpool, walk/ride a
bike, turn off unneeded lights/electrical appliances,
don’t let H20 run, place recyclables in marked
containers

42. A Case Study-
UDAIPUR

43. Mining and quarrying in Udaipur
About 200 open cast mining and
quarrying centers in Udaipur, about
half of which are illegal are involved
in stone mining include soapstone,
building stone, rock phosphate and
dolomite.The mines spread over
15,000 hectares in Udaipur have
caused many adverse impacts on
environment.

About 150
tones of
explosives are
used per
month in
blasting.The
overburden,
wash off,
discharge of
mine water
etc. pollute
the water.

The Maton mines have badly polluted the Ahar river.The hills around the
mines are devoid of any vegetation except a few scattered patches and the
hills are suffering from acute soil erosion.

The waste water
flows towards a
big tank of “Bag
Dara”. Due to
scarcity of water,
people are
compelled to use
this effluent for
irrigation
purpose.

The blasting activity has adversely affected the fauna and the
animals like tiger, lion, deer and even hare, fox, wild cats and birds
have disappeared from the mining area.
