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%

The test ore is a kind of relatively high grade of sulphide copper-lead ore, the difficulties of test is the effective separation of copper and lead, the lead grade of 13.08% and copper grade of 1.33% in comprehensive core sample. After the exploring test of principle flow sheet, the flotation process of depress lead and float copper is used. As a result, the grade of copper is 25.25% and lead is 6.23% in the copper concentrate, the grade of lead is 51.23% and copper is 2.44% in lead concentrate. The test research has certain guiding significance about copper and lead separation on production.
