Copper Sulfide Ore

Through the processing of mineralogical study on a copper ore from Jilin province in China, it found that the copper exist mostly with the form of chalcopyrite, and others exist with the form of copper oxide minerals which with complex ingredient. The copper oxide minerals are due to the altered of the edge of chalcopyrite, and have not formed the independent copper oxide ore. It belongs to unconventional hard-to-beneficiate copper ore. Coarse grinding fineness and bulk floatation was used to recover the copper oxide ore and copper sulfide ore by using amino double phosphoric acid and butylamine dithiophosphate as the collector. This process was similar to the carrier flotation and achieved an effective processing of the copper oxide ore and obtained a high-grade copper concentrate assaying 15.8% with a high recovery of 82.4%.
