Green Mining Massachusetts Institute of Technology

In situ mining (see mining solution page) can be more environmentally friendly than underground mining and is cheaper than many mining methods (Ulmer Scholle, 2008). However, in situ mining cannot be implemented in all cases as the ore needs to be beneath the water table (the level at which the ground is saturated with water) and it needs to be porous enough to let the leaching solution dissolve (Topf, 2011).

Compared to other mining methods, room and pillar mining is a low cost method with a low recovery rate (since some ore is left behind in pillars). Yet, the method causes very little dilution as the contact between ore and waste is limited due to the waste being on top and ore being at the bottom.

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.
