in situ copper mining
Electro Copper Refining Elmhurst College
Insitu Copper Mining: Another type of mining being tried by BHP at Florence, AZ is insitu copper mining. A weak acid solution is injected in wells to dissolve the copper in the ore without removing it. The concentrated copper solution is then pumped out of recovery wells.

What is In Situ? Cavalier Energy Inc.
What is In Situ? There are two different methods of producing oil from oilsands: openpit mining and in situ (latin, meaning "in place") technology. Bitumen close to the surface is mined. Bitumen deep within the ground is produced in situ using specialized extraction techniques.

Green Mining Massachusetts Institute of Technology
Insitu 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.
