Installation of an APU post copper liberator results in significant additional cost savings due to reduced acid consumption in the refinery and reduced neutralization requirements for treating the de-copperized bleed. Furthermore, nickel metal can also be recovered from the de-copperized, de-acidified bleed stream.

Electrolytic refining (electrorefining) is a process used to make impure copper pure. Unlike aluminum, copper metal is fairly easy to obtain chemically from its ores. By electrolysis, it can be refined and made very pure—up to 99.999%. The electrorefining is at the heart of not only copper purification, but the production of sodium hydroxide

The sulfide concentrates are typically smelted in such furnaces as the Outokumpu or Inco flash furnace or the ISASMELT furnace to produce matte, which must be converted and refined to produce anode copper. Finally, the final refining process is electrolysis. For economic and environmental reasons, many of the byproducts of extraction are reclaimed.
