Copper Mining and Production Processes Explained

Copper Mining and Production Processes Explained

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SXEW (solvent extraction/electrowinning).

Solvent extraction has been routinely used for copper refining since its invention in the 1960s, and it is suggested that well over 10% of refined copper production from ores is obtained by solvent extraction, accounting for millions of tonnes of metal. It is even more popular for refining copper from scrap.

Copper Recovery by Solvent Extraction. A common method of copper recovery from oxide ores is dump leaching in which the excavated ore is crushed and dumped on an impervious surface in lifts of anything from 10 to 100 ft deep. Sulphuric acid is sprayed onto the levelled off dump via a network of pipes designed to give even distribution.

The leaching, solvent extraction and electrowinning (LXSXEW) process is a widely used method in the production of copper from lowgrade oxidized ore. Copper is the most common metal to be processed by LXSXEW, but the process can also be used to extract, purify and concentrate other metals, such as nickel, cobalt and zinc.

The solvent extraction phase of treatment occurs in two stages. During the initial phase an organic solvent is used to recover copper ions contained in the pregnant leach solution, exchanging them with hydrogen ions in the acid. The final phase of the solvent extraction process employs a strong acid to strip the copper from the organic solution
