某铜硫尾矿中钨的工艺矿物学研究

The Process Mineralogy of Tungsten from a Copper-sulfur Tailings

针对某含钨铜硫尾矿,采用化学分析、光学显微镜检测和先进的MLA矿物自动检测技术等手段进行工艺矿物学研究。研究结果表明,该尾矿WO3品位0.23%,达到综合利用指标要求,其中主要钨矿物为白钨矿和少量黑钨矿。该尾矿钨的理论品位WO379.41%,理论回收率约为84%,若仅选别白钨矿,钨的理论回收率约为81%。

This paper studies the process mineralogy of copper-sulfur tailings through chemical analysis, microscope, advanced Automatic Quantitative Mineral Technology MLA. The results indicate that the tungsten content in the tailings is 0.23 %, which meets the comprehensive utilization requirements. The major mineral in the tailings is scheelite in addition to small amount of wolframite. The theoretical WO3 grade and tungsten recovery rate of the tailings are 79.41% and 84 %, respectively. However, the theoretical tungsten recovery rater is about 81% if recovering scheelite only.
