Abstract

In order to improve the recovery of a certain refractory half oxidized gold ore in Qinghai Province,based on the process mineralogy research,the ore leach test,flotation and flotation tailings CIL experiment was carried out,then the environmental gold agent and sodium cyanide contrast leach test.The results show that respective used 1#,2# environmental leaching gold agent and the sodium cyanide,the gold leach rate was 80.07%,79.71% and 80.80% when the -74 microns content is 91.81%.Used flotation and then CIL leach process,the grade of the flotation concentrate is 125.94×10-6,the recovery of flotation is 73.72%,the flotation tailings leach test used 1#,2# environmental leaching gold agent and the sodium cyanide,the dressing comprehensive recovery respectively reached 92.67%,93.62% and 94.99%,when the -74 microns content is 83.64%.
