摘要: 云南某锡矿由于锡矿矿石成分复杂、有价金属多、有用矿物的矿石类型为矽卡岩和矽卡岩硫化矿石且其嵌布粒度较细,虽经过浮—重—浮—磁等选矿方法处理后,其尾矿中仍有可供综合利用的有价矿物,采取了重—磁选联合流程选别后取得了一定的经济效益,实现了资源的综合回收利用。

Abstract: A tin ore of complex composition is from Yunnan province, with rich valuable metals, and valuable minerals mainly exists in form of skarn & skarn—sulphide ore type which are finely disseminated. Although after flotation—gravity concentration—flotation—magnetic separation treatment, there are also valuable minerals in the ore. Economic benefits was achieved through comprehensive recycling and utilization of the ore by gravity—magnetic combined separation process.

Key words: Tin tailings, Flotation, Gravity—magnetic combined separation process
