Valves for copper leaching, solvent extraction Neles
The leaching, solvent extraction and electrowinning (LX-SX-EW) process is a widely used method in the production of copper from low-grade oxidized ore. Copper is the most common metal to be processed by LX-SX-EW, but the process can also be used to extract, purify and concentrate other metals, such as nickel, cobalt and zinc.

Solvent Extraction and Electrowinning Support PPM Global
Solvent extraction equipment consists of a series of mixers and settlers. Here’s where the mixers receive the solvent from a previous settler in the process. This would be an aqueous solution: either a leach solution or electrolyte from the electrowinning process. The two solutions are mixed then discharged by overflow to the adjoining settler.
