  • SXEW (solvent extraction and electrowinning) KGHM

      SXEW 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 SXEW reactor, the first process to take place is solvent extraction, which involves setting and
