Studies on solvent extraction of copper and cyanide

2009-9-30  Copper can be effectively extracted from alkaline cyanide solutions by both extractants. The free cyanide remains in the aqueous phase due to the preferential extraction of Cu (CN) 32− over Cu (CN) 43− and CN − by the extractants. The selectivity of the metals with the extractants under different cyanide levels has been examined.

SX Solvent Extraction Process Principles Theory

2017-2-1  All of the copper can be extracted at low pH (1.5 to 2.0) before the system is adjusted with ammonia to higher pH (9.0 to 9.5) where the nickel is extracted. This type of scheme has been used on a commercial scale at the S.E.C. Corporation in El Paso, Texas, for the recovery of copper and nickel from a refinery bleed stream.
