摘　　要：安徽某铜矿山现场采用优先浮铜—选铜尾矿磁选回收磁铁矿及磁黄铁矿—磁选尾矿浮选回收黄铁矿的工艺流程。浮选作业均采用常规浮选机,当原矿品位降低时,精矿铜品位难以达到设计指标。为提高铜精矿品位,在实验室试验的基础上,分别采用CCF型浮选柱和旋流-静态微泡浮选柱进行半工业试验。现场结果表明:采用浮选柱的精矿品位均高于同期现场精矿品位,其中CCF型浮选柱的精矿品位高达21.01%,比同期生产指标提高了2.9个百分点,旋流-静态微泡浮选柱的精矿品位为19.96%,比同期现场生产指标提高了1.05个百分点。说明CCF型浮选柱更适合于处理该矿石。The process flow of preferential floating copper-magnetite and pyrrhotite recovery by magnetic separation from copper tailings-pyrite recovery by flotation from magnetic separation tailings was adopted in a copper mine on-site process in Anhui.Flotation operation all used flotation machines in the mine.When the grade of raw ore is reduced,the copper grade of concentrate is difficult to reach the design index.In order to improve the grade of copper concentrate,on the basis of laboratory tests,CCF flotation column and cyclone-static microbubble flotation column were used for semi-industrial tests.The test results show that the concentrate grade of the flotation column is higher than that of the on-site concentrate in the same period.The concentrate grade of the CCF flotation column is up to 21.01%,which is 2.9 percentage points higher than that of the production index in the same period.The concentrate grade of the cyclone-static microbubble flotation column is 19.96%,which is 1.05 percentage points higher than that of the production index in the same period.It indicates that CCF type flotation column is more suitable for the treatment of the ore.
