摘要
提高尾矿资源综合利用水平是选矿技术未来的发展趋势,针对重选后的高硅细粒级锡石尾矿,采用一种新的环保高效选矿工艺,大幅度提高了该尾矿锡石的综合回收。当给矿锡品位1.24%时,全流程闭路试验可获得锡精矿含锡32.17%,回收率75.38%的选矿指标。
It is a trend in development of mineral processing technology to improve the level of tailings comprehensive utilization in the future. This thesis focuses on the high silicon fine cassiterite, which is the tailings of gravity separation, developed a new kind of environmental protection and high efficiency mineral processing technology. It greatly improves cassiterite comprehensive recycling of the tailings. After complete closed-circuit flow test, the tin concentrate with Sn grade of 32. 17% and recovery ratio of 75.38% was obtained.
