2019-6-14 · 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.

Copper Mining and Processing: Processing of Copper

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

NHE Copper Metal Recovery Acid Mine Drainage

We selectively recover copper and other valuable metals and minerals from the acid mine drainage (AMD) process using a high purity cathode. AMD, or acid rock drainage, occurs naturally within some environments as part of the rock weathering process, but is exacerbated by large scale earth disturbances found with copper mining or exhausted heap leach operations.
