| Abstract: | There is abundant polymetallic ores in Qinghai province.These ores contain some important valuable elements.But,when the single flotation flowsheet or direct leaching technology is adopted,the reasonable techno economic targets for grade of cobalt,nickel,copper and gold in concentrates can not achieved.However,over 90% extraction percentages of these metals were achieved when the oxidation pretreatment hydrometallurgical leaching technology developed by authors was adopted. |
