Abstract:Taking high sulfur copper zinc ore as the research object, based on the study of process mineralogy, according to the characteristics of the ore, the influence of grinding fineness, adjusting agent type, and collecting agent type on copper zinc sulfur recovery is studied, and suitable mineral processing technology and reagent system are developed. The experimental results show that using the process of two coarse, one scavenging, five fine, and three fine sweeps of copper and zinc can obtain a copper zinc mixed concentrate with a copper grade of 6.90%, a copper recovery rate of 85.54%, a zinc grade of 39.48%, and a zinc recovery rate of 94.76%; By adopting a process of one coarse, one scavenging, and three fine, a sulfur concentrate with a sulfur grade of 49.09% and a sulfur recovery rate of 72.48% can be obtained, with a sulfur operation recovery rate of 85.03%. This study can achieve efficient recovery of copper, zinc, and sulfur from high sulfur copper zinc ores, providing important guidance for the comprehensive development and utilization of this type of mining resource.
