中文摘要: 云南文山都龙多金属矿分选难度大,硫粗精矿中砷和杂质含量高,严重影响企业经济效益。论文在对硫粗精矿进行工艺矿物学研究的基础上,采用“磁选-深度细磨-浮选”的联合工艺对硫粗精矿进行提质降杂试验研究,并对锌进行回收。所得硫精矿中S、Zn、As品位分别为36.66%、2.72%、0.63%,其中S的回收率为75.73%,锌精矿中Zn品位为40.68%,回收率为52.63%。硫精矿的质量明显提高,提质降杂效果明显,同时还实现了锌的回收。
Abstract:The Dulong polymetallic ore in Wenshan, Yunnan province is difficult to separation, so that the high content of arsenopyrite and impurities in the crude sulfide concentrate, which seriously affects the economic benefits of the enterprise. Based on the study of mineralogy of crude sulfur concentrate, combining process of "magnetic separation-deep grinding-flotation" was used in this paper to improve the quality of crude sulfur concentrate and recover zinc. The grades of S, Zn, and As in the obtained sulfide concentrate were 36.66%, 2.72%, and 0.63% respectively, the recovery of S was 75.73%. The grade of Zn in the zinc concentrate was 40.68%, and the recovery was 52.63%. The quality of the sulfide concentrate is obviously improved. The effect of improving quality and reducing impurities is obvious. Simultaneously, the recovery of zinc is also realized.
