Flotation Test of High Sulfur Copper Ore in the Northwest in Yunnan

Zhi Guo Zhang, Quan Jun Liu, Jin Cheng Ran

Abstract

The experimental ore belongs to a kind of typical high sulfur ore,which makes it to be a refractory ore.The copper in the ore has a relative high grade which comprehensively reaches 3.78% ,with the chalcopyrite occurs the main form.After a serious of condition tests,a final flowsheet with once roughing,twice cleaning and twice scavenger is determined.Through a closed-circuit,it could obtain copper concentrate with grade of 20.91% and recovery of 91.61%
