摘要
Abstract
Taking a certain arsenic-containing gold concentrate as an example,a gold extraction experiment is conducted,and multi-element analysis is carried out on the ore sample,the processes of gold concentrate roasting,roasting sand acid leaching,and leaching residue cyanide leaching are studied to obtain the main process conditions,and the gold leaching recovery rate is obtained under the optimal gold concentrate roasting-acid leaching-cyanide conditions.Research has found that the decarbonization rate of high arsenic gold concentrate during roasting is 98.98%,the desulfurization rate is 98.23%,and the arsenic removal rate is 94.06%.Under the optimal process conditions,the leaching rate of gold is 93.87%.关键词
