SX-EW (solvent extraction and electrowinning) | KGHM

SX-EW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid. Folowing leaching, the pregnant leaching solution is transported via a drainage system to the next stage. In an SX-EW reactor, the first process to take place is solvent extraction, which involves setting
