| Abstract: | The gold particle size of Nancha gold ore is fine and it is wrapped by sulfide minerals,it has a close relationship with arsenic,the flotation recovery is high,the gold leaching rate of arsenic-bearing gold concentrate canide is only 30%,and it is difficult to recovery use.Using bacterial oxidation-cyanide gold extraction process and continuous expansion experimental research,the gold leaching rate reach 97.00%,the indicator is more ideal,and we better resolve the refractory problem of arsenic-bearing gold ... |
