Abstract
Results of the investigation of reagent regimes and technological operations of gold recovery into concentrates from the ores of parent deposits and technogenic gold-containing raw material of the Krasnoyarsk Territory. Investigations were carried out at the Institute of Chemsitry and Chemcial Technology SB RAS and at the Institute of Nonferrous Metals and Materials Science of the Siberian Federal University during the recent decade. Dependencies of ore concentrability on the mineral and granulometric composition were established. Ways to impromenet of the quality of gold-containing concentrates are shown, new floatation agents are recommended along with new operations of fine gold concentrating, including afterconcentration of old dumps and tailings. Technological operations for the treatment of different hypergene deposits based on stagial combination of various mining and concentrating technologies were rpopsoed for the first time.
