Green Mining - Massachusetts Institute of Technology

In-situ leaching mining (see the mining background page) has been introduced as the required mining method for those new mines that can physically implement this technology. Saponification, a step of the refining process that leaves the wastewater highly toxic, can be improved through a newly discovered method that eliminates the need for ammonia.

Environmental Risks of Mining

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
