Copper Mining And Extraction Sulfide Ores

Copper Mining And Extraction Sulfide Ores

Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. Advantages of this process are See for further information on the leaching process.

A process is provided for heap leaching ore to recover nickel. The process is particularly effective for ores that have a tangible clay component i.e. greater than about 10 by weight. The process includes siing the ore where necessary forming pellets by contacting ore with a lixiviant and agglomerating. The pellets are formed into a heap and leached with sulfuric acid to extract the
