Copper Mining and Production Processes Explained

The copper is purified to 99.99% by electrolysis. The production route described above shows the progression from a rock containing about 0.2% copper to a copper cathode of 99.99% purity. Leaching. Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid.

What Are the Effects of Leaching? | Sciencing

Mar 13, 2018 · This process is called leaching. Under normal circumstances, minor levels of leaching occur with typical rainfall, and the breakdown of organic materials on the surface resupplies the soil. In the case of excessive rainfall or irrigation, the effects of soil leaching can be more dramatic.
