Abstract
Under analysis is interaction between 1-phenyl-2,3-dimethylaminopyrazolone-5 (AMD) and copper in solution and on the surface of chalcopyrite. It is found that AMD experiences chemical adsorption on the surface of chalcopyrite as a compound with copper. Effect exerted on adsorption of AMD agent on copper sulfide by ammonium rhodanate (NH4CNS), introduced as an additional ligand, or its mixture with acetic acid is defined. Based on the analytical research and the analytical chemistry data, the type of adsorption on the surface of chalcopyrite is determined. The flotation tests on monomineral fraction of chalcopyrite and pyrite, and copper sulfide ore prove selectivity of AMD in separation of chalcopyrite and pyrite.
