Main Body

Distribution of rare earth elements:

Recent lithium reserves have been discovered in Kargil district and Mandya region of Karnataka in India.

Uses of Rare earth mineral:

1Production process in semi-conductor industries
2In li-ion batteries and other battery-energy storage infrastructure
3Manufacture of electric-vehicles
4Production of solar panels modules
5Use in computers, robots, mobile phones etc.

Environmental impact of its extraction:

Impact on surrounding ecosystem through hard rock extraction technique requiring open-cast mining & landfills
Change in landscape
Land degradation

Impact on living ecosystem includes:

1Deep sea mining disturbs sea-environment
2Coal reefs
3Causes siltation
4Leads to eutrophication
5Disturbing the ecology of the region
6Change in water cycle
7Moreover, disasters like earthquake, landslide disrupt infrastructure.

Therefore, proper environmental impact assessment must be taken over by the mining industries before mining. Also, in so many regions of India border security angle can also emerge.

Uses of Rare earth mineral (continued):

1Production process in semi-conductor industries
2In li-ion batteries and other battery-energy storage infrastructure
3Manufacture of electric-vehicles
4Production of solar panels modules
5Use in computers, robots, mobile phones etc.

Environmental impact of its extraction:

Impact on surrounding ecosystem requires hard rock extraction technique requiring open-cast mining & landfills
Change in landscape
Land degradation

Impact on living ecosystem includes:

1Disasters can take place
2Hard work extraction technique require open-cast mining & landfills
3Change in landscape
4Land degradation
