Valves for copper leaching 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.
