It's electric! Technique could clean up mining of valuable rare earth
5:25 PM ET. By Dennis Normile. In-situ leaching to extract rare earth elements, such as at this mine in southern China, leads to water and soil pollution and large volumes of toxic waste. A Chinese group has proposed a new, cleaner approach that relies on electric currents to separate the elements from the soil. Kevnmh/Wikimedia Commons.

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.
