Abstract

The article presents studies into the microwave treatment effect on higher recovery of noble metals from rebellious carbonic ore. The rate of refractoriness of carbonic concentrates was determined using a package of thermal testing techniques. Bitumen is an additional criterion of the refractoriness rate of mineral dressing products. The influence of treatment time on heating of a sample is studied at different microwave capacities. The process of heating of dry concentrates in electrolytic solution is analyzed. The applicability of microwave treatment of flotation concentrates toward higher recovery of gold from rebellious carbonic ore is proved.
