Process description: Copper may be extracted from

Copper may be extracted from copper containing ore via a leach and solvent extraction process. Copper is first removed from the ore via a 'heap leach'. Leach acid is passed through a bed of copper ore and the copper is dissolved into an aqueous solution. It is assumed that all copper is dissolved into the leach acid solution.
