摘要： A method for inhibiting crud formation and organic in aqueous solvent and aqueous in organic solvent entrainment in the solvent extraction of copper from an aqueous sulfuric acid pregnant leach solution is disclosed. The method comprises adding an antifoam formulation stable at a solution pH of about 1 to 2 is added. A preferred antifoam formulation comprises a glycol ester and an alkyl phenol ethoxylate in a paraffinic oil solvent added to the acid solution.
