Valves for copper leaching, solvent extraction and

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.
