Recovery of Copper by Solution Mining Methods

Solution mining operations are designed to maximize copper recovery at a particular locality, while complying with all regulatory standards set forth in the permits that govern the design and operation of these projects (Weeks and Millenacker, 1988). A number of methods are employed to achieve this goal.

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 ...

Copper Cementation System for Small Scale Mining Operations

2017-08-17  Analyses of starting and ending solutions indicated that copper recovery of 95.5 percent was attained. Iron consumption was 1.09 pounds iron per pound of copper. Observations made during the test revealed that the cemented copper formed a loosely adhering spongy mass that subsequently was easily removed from the iron.

Ore Dilution Recovery in Mining

2017-04-05  Recovery in block caving varies with conditions and is influenced by the amount of dilution the ore can stand, since high recovery usually involves high dilution also, and the amount of dilution permissible depends on metal prices. Thus, if the minimum grade of ore that it is profitable to handle is 1 percent copper, drawing should stop when, owing to dilution, the grade falls below this ...
