Abstract

Abstract: The efficient utilization of a refractory gold ore was investigated. The results indicated that gold concentrate containing gold 54.20 g/t at recovery of 73.23% and tailing containing gold 1.43 g/t could be obtained by flotation. Cyanide leaching process was used to treated the gold concentrate and tailing. Pregnant solution with recovery of 53.49% and leaching slag of gold concentrate at recovery of 36.21% were produced. The total recovery of gold could reach 89.70%. The process of flotation and cyanide leaching provides scheme for developing and utilizing of this refractory gold ore.

Key words: Refractory gold ore, Flotation, Cyanide leaching
