EIA is a decision making tool for developmental projects (Mining, construction of dams). It will have environmental implication in changing the variables such as quality of air, ground water, soil in that area. The purpose of assessment is to ensure that decision makers consider the environmental impacts to implement the project EIA helps us to measure or predict the impact of any developmental projects on the environment. Mining refers to Extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. Metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Large scale mining pollution contaminates all living organisms within the body of water Affects environment adversely Results in deforestation

4. ❖ Extraction of valuable minerals or other geological materials
from the Earth, usually from an ore body, lode, vein, seam, reef,
or placer deposit.
❖ Metals, coal, oil shale, gemstones, limestone, chalk, dimension
stone, rock salt, potash, gravel, and clay.
Mining

5. ❖ Mining is the extraction of minerals and metals from earth
❖ Mn, Cu, Ni, Au, Ag, Fe, and diamonds are some examples
❖ Minerals and metals are very valuable commodities
❖ For eg.
i. Copper (Cu) – Copper wiring
ii. Nickel (Ni) – Jewellery
iii. Ni, Li and Cadmium (Cd) - Batteries
iv. Iron (Fe) - Utensils

8. ❖ This pollution contaminates all living organisms within the body
of water
❖ Affects environment adversely
❖ Results in deforestation
Large scale mining

9. ❖ When mining pits fill with water, they become stagnant water
pools
❖ Create breeding ground for mosquitoes etc
❖ River dredging – Fish and other living organisms die and the
rivers get obstructed for navigation
❖ Destruction of agricultural land and pollutes drinking or fishing
waters
❖ Extraction of sulphide ores inevitably produces sulphuric acids
and metal ions
Small scale mining

10. ❖ Erosion
❖ Sinkholes
❖ Deforestation
❖ Loss of Biodiversity
❖ Significant Use of Water Resources
❖ Dammed rivers and Ponded waters
❖ Wastewater Disposal Issues
❖ Acid Mine Drainage and
❖ Contamination of Soil, Ground and Surface water
