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.

North America is About to Get Its Largest

Some big copper mines have devastated the surrounding countryside due to acid mine drainage. Ducktown in Tennessee (see above) is a famous site still recovering from copper mining and smelting in the 1900s-60s. The Butte copper pit, once the mine closed, became one of the first Superfund sites thanks to a lake that filled the mine pit with a pH of ~2.5 so acidic it killed birds that landed ...
