摘要：
The gold ore is oxidized ores, and it is not suitable for flotation separation. The cyanide leaching is used for the recovery of gold. Experimental studies of cyanidation leaching for a oxidized gold ore were carried out. The factors that influence leaching such as grinding size, sodium cyanide quantity, pulp density, extraction time and segmentation leaching were conducted. And experiment pretreatment test with the copper ion which influences leaching. The results demonstrated that the good index of leaching rate 90.11% could be reach.
