Experimental Study on Copper-sulphur Separation for a Complex Refractory Copper Sulfide Ore
摘要
Abstract
According to the characteristics of a complex refractory Copper-sulfur ore,the content of copper oxide and soluble copper salt was found higher in the mine.And a lot of copper ions was found through the determination of flotation pulp,this caused the separation of copper-sulfur was more difficult.According to the characteristics of the ore,the experiment process of preferential flotation of copper process was made,and the reasonable technological condition was determined by the conditions of test,effectively solve the problem that a large number of copper ions caused the separation of copper-sulfur was more difficult in the flotation process.In the condition of the grinding fineness was-0.074 mm 75 ％,inhibitors was used of lime and Sodium sulfide,and after the Copper-sulfur separation of flotation process of first float copper and sulfur separation from crude pulp,obtained the copper concentrate of the copper grade is 16.21％,recovery rate is 84.21％,sulfur concentrate of the sulfur grade is 45.14％,recycling rate is 82.11％.关键词
