Abstract
The cyanide tailings of a gold ore in Xinjiang contains Cu0.29% ,Pb0.27% ,Zn0. 66% , Au0. 65t/g and Ag6. 2t/g. It is difficult to recover lead and zinc for their serious oxidation. The copper is the main object to recover. The reagent system and the flotation condition were explored. When the flowsheet of one roughing, one scavenging and two cleaning was adopted, using Na2SO3+ZnSO4 as depressant for zinc and sulfide and PAC as collector for copper,the copper grade of 15.27%and the recovery of 80.55% ,the gold grade of 8.32g/t and the recovery of 23. 46% and the silver grade of 129g/t and the recovery of 37.69%were obtained,realizing the comprehensive recovery of copper in the tailings.关键词
