There is 0. 58% copper,0. 75% lead,and 3. 01% zinc in a poly-metallic sulfide ore from Yunnan,with low content of harmful element arsenic. Beneficiation experiments were conducted on the ore to develop and utilize the ore. The re-sults indicated that,at the grinding fineness of 85% passing 0. 074 mm,with sodium thiosulfate,sodium hexametaphosphate, and humic acid as gangue inhibitors,sulfide zinc sulphate as zinc mineral inhibitor,and ethyl xanthate as collector via copper and lead bulk preference flotation,separation of copper from lead for bulk concentrate using slime as pH modifiers,EMY-306 as gangue inhibitors,Z-200 as collector,zinc flotation using copper sulfate as the activator,butyl xanthate as collector,copper concentrate with 26. 09% Cu and recovery of 71. 25%,lead concentrate with 48. 82% Pb and recovery of 69. 21%,and zinc concentrate with 49. 80% Zn and recovery of 87. 78% are obtained respectively. Good beneficiation test results had been ob-tained,which provide technique basis for reasonably recovery of the resource.
