Not So "Green" Technology: The Complicated Legacy of Rare Earth Mining

For every ton of rare earth produced, the mining process yields 13kg of dust, 9,600-12,000 cubic meters of waste gas, 75 cubic meters of wastewater, and one ton of radioactive residue. This stems from the fact that rare earth element ores have metals that, when mixed with leaching pond chemicals, contaminate air, water, and soil.

Sustainable Lithium Extraction: How is Lithium Mined and …

Mining lithium from evaporating ponds is a unique method of lithium extraction. It involves pumping lithium-rich brine into large evaporation ponds and allowing the water to evaporate over time. The concentrated brine is then processed to extract lithium, similar to the process followed in brine extraction.
