SX-EW (solvent extraction and electrowinning) KGHM

In an SX-EW reactor the first process to take place is solvent extraction which involves setting and simultaneous purification of the post-leaching solution. Later the purified solution undergoes copper electrolysis which results in cathode copper that meets quality and quantity criteria enabling its sale.

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 SX-EW (solvent extraction/electrowinning).
