In Situ Copper Mining

Excelsior Mining Corp - In-Situ Recovery

The optimal conditions to use In-Situ Recovery for copper mining follow a few guidelines. Firstly, the host rock needs to be fractured enough to allow for the solution to permeate through and dissolve the copper resource. The more fractured the rock, the more surface area there will be for the copper to be dissolved. Secondly, the copper resource must be below the water table. Without the ...

Recovery of Copper by Solution Mining Methods

mining: 1) in-situ and 2) in-place. In-place solution mining employs permeability enhancement techniques such as blasting or previous mining activities (i.e. block-caving) to fragment or increase the permeability of the rock prior to applying a leaching solution to liberate a desired commodity from the ore. In-situ methods rely solely on the naturally occurring permeability of the ores. Copper ...
