ABSTRACT:
Copper is recovered from dilute, ammoniacal, copper containing solutions by adding ferrous ions to the solution to precipitate metallic copper and iron oxides. The mixed precipitate is separated from the aqueous raffinate. The precipitated copper and iron oxides are separated from each other to enable the copper to be recovered.
