Copper Nickel Solvent Extraction

Three extraction stages resulted in >99pct extraction of nickel, substantial copper extraction, and essentially no cobalt extraction from leach liquors. A crowd stage reduced the ammonia loading on the solvent by maximizing nickel loading. Residual ammonia was removed from the loaded solvent with a pHcontrolled scrub.
