DI-SEP® SX Electrolyte Filter

Pioneered in 1980, Smith & Loveless DI-SEP® SX Filters are high volume pressure filters designed exclusively to purify electrolyte fluids in copper mining/electrowinning facilities. DI-SEP® SX Filters installed prior to the electrowinning stage first remove organic materials present in the electrolyte, typically achieving removal efficiencies of greater than 90 percent. Because the commercial success of copper is dependent on its final quality, DI-SEP® SX Filters serve as an important step in yielding a finer copper product.

DI-SEP® SX Filter systems, which comprise tank vessels, a piping/valve skid, and PLC-driven controls and instrumentation, have been installed at numerous copper SX-EW mines throughout North and South America, Australia, and now, Europe.
