Abstract

Abstract

In order to solve the problem of coarse and unreasonable particle size composition distribution in Dongguashan, the particle size composition of floating particles was optimized by adjusting the proportion of grinding medium based on the particle size distribution of grinding products and the dynamics properties of ores. The results showed that the size scheme of one stage of grinding media in Dongguashan is m (φ60):m (φ40):m (φ30):m (φ25) = 40:10:30:20. The yield of -0.1+0.01mm particles in grinding mineral products could be increased by 2.28% used the recommended scheme. Compared with the recommended scheme and the field scheme experienced flotation closed circuit test with one rough and two fine sweeps, the recovery rate of copper concentrate used recommended scheme was 90.11%, which was 1.34% higher than that of the field scheme. And the concentrate grade used recommended scheme was 0.94% higher than that of the field scheme. According to the screening and detection analysis of the flotation tailings, the recovery of copper in -0.1+0.01mm particles of grinding minerals in the recommended scheme was better than that in the field scheme. The recommended medium ratio scheme was used to optimize the particle size composition of grinding minerals, which effectively improved the flotation index of copper in Dongguashan.
