Copper Mining and Extraction Sulfide Ores

Open pit: 90% of ore is mined by this method. 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.

How Mining Companies are Reducing the

Mining leaves an eyesore on the land. By ripping open mountains to extract the ores within, it sometimes leaves areas unusable after the mining companies have left. We can't go on this way, and politicians agree. It's why mining companies are working to reduce the environmental impact of mining through green mining processes. Green mining doesn’t apply exclusively to the mining process ...
