  • Copper LXSXEWNelesReinventing reliability

    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.
