摘要
针对云南某选厂浮选硫精矿中的金以细粒包裹体状赋存于黄铁矿中的性质,采用重浮-焙烧-浸出工艺回收硫精矿中的金、铁、硫.实验结果为:硫以二氧化硫形式回收,回收率为98.24%;金的浸出率为85.48%;浸渣铁品位为60.48%,回收率为98.44%.
Gold as fine-grain inclusions in the pyrite concentrate in Yunnan province was found.A method of gravity separation and flotation separation-roasting-leaching was used to separate Au,Fe and S in pyrite concentrate.The results showed that the recovery of S in sulfur dioxide was 98.24% and Au was 85.48% in cyaniding leached liquor,and leached residue could be as iron concentrate with the grade of Fe 60.48% and the recovery of 98.44%.
