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

What is InSitu Recovery Mining? EnviroCopper

Metals (Copper, Gold etc) are recovered ‘In Situ’ by firstly dissolving the commodity in place and then extracting them using a system of injection and extraction bores or wells. Most times ISR accelerates what is already happening naturally within the bedrock and water table. ISR is the same technology used in the remediation of contaminated sites where it is called “pump and treat

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

What is “In Situ” Mining? Black Hills Clean Water Alliance

In situ leach mining (ISL) is a method of uranium mining where hundreds of wells are drilled in a “grid pattern” over an ore body that is located in a groundwater aquifer. Water mixed with sodium bicarbonate concentrate is pumped down into the aquifer, across the uranium ore bed, and them up and out other wells. The mining solution is injected into the aquifer under pressure in order to
