Effects of Sodium Chloride Leach Solution Additive on Simulated In situ Leaching of a Chalcopyrite Ore

摘要

The Bureau of Mines conducted research to simulate in situ leaching of a porphyry copper sulfide ore. The purpose was to determine the effects on copper leaching of additions of NaCl to conventional sulfate leach system and to analyze the oxidant requirements and the oxidation products that resulted from leaching of the sulfide minerals in the ore.
