Cyanide Leaching Experiment Research on Gold - Bearing Tailings

Mei Guang Jiang, Quan Jun Liu, Hong Xiao, Jun Yang

Abstract

The gold grade of the gold mine is high，because of the him particle size is fine，after flotation and gravity separation,the grade of gold is 3.5g/t,In order to increase economic efficiency and improve the resource utilization,this paper studies cyanide leaching of gold ore on the tailings,With studying experiment,the grade of gold is approximately 0.17g/t.the leaching rate of gold is nearly 95%.
