Electrokinetic Mining Enables Greener Extraction of Rare Earths
As beneficial as mining has been to the development of human civilization, the impact it has had on the environment is devastating. Mineral extraction over the centuries has at times contributed to the contamination of local streams and wetlands, deforestation, soil erosion, contamination and alteration. The global mining industry is estimated to produce roughly 4% to 7% of the worldwide greenhouse gas emissions. With the environmental impacts of industries such as mining becoming clearer by the day, there has been increased interest in mining processes that consume less energy and have a smaller environmental impact.
