THE RESEARCH ON MINERAL PROCESSING TECHNOLOGY OF CERTAIN Zn-Fe POLYMETALLIC ORES

The systematic test research of optimized parameters for processing certain Zn-Fe polymetallic ores has been done in this paper.The separation indices show that,the collector ZC newly developed has better selectivity and stronger ability for collecting sphalerite.Adopting flotation-magnetic flowsheet in the conditions of optimized processing parameters,the best separation indices of Zn and Fe have been obtained in closed circuit tests.The grade and recovery of the Zn-concentrate are 59.19% and 98.06% respectively.Both of Ag and In are enriched in Zn-concentrate,their grades are 339g/t and 122g/t respectively,and their recoveries are 96.28% and 71.32% respectively.The grade and recovery of the Fe-concentrate are 65.30% and 66.62% respectively.
