Abstract

Methods are provided for precipitating arsenic from an acidic sulphate copper leach solution as a stable scorodite precipitate prior to any refining steps. The method utilizes pyrite or chalcopyrite in the leach train as the primary source of ferric ions for the precipitation of scorodite.
