Selectivity in the flotation of copper with xanthate

The interaction energy of the studied complexes is −56,39 kcal/mol for Cu, −25,86 kcal/mol for Cd and −7,29 kcal/mol for Zn complex. It was found that xanthate binds to copper over zinc and cadmium elements. Experimental results show that for copper, cadmium and zinc, the flotation effectiveness are 94,68%; 67,18% and 36,92% respectively.
