solvent extraction copper leaching

TENORM: Copper Mining and Production Wastes Radiation

During insitu leaching, rather than physically mining and removing overburden to reach copper deposits, chemicals are introduced into ore bodies using injection wells. The PLS is then captured in production wells, collected and later processed. Solvent extraction. Once PLS is leached, it is sent to a solvent extraction plant to remove the copper.

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).
