摘要
针对广西某尾矿中难回收的细粒锡石,进行了高效再利用选矿工艺技术研究。试验采用二段分级-离心重选-浮选的选矿工艺回收细粒锡石,获得了较好的选矿试验指标:锡精矿锡品位17.02%,锡回收率60.16%,实现了尾矿中的细粒锡石的高效回收利用好。
Aimed at the ultrafine cassiterite which is difficult to recycle from the tailings in Guangxi, the research on the benefi- ciation technology was carried out for the efficient recovery and reuse of ultrafine cassiterite. The beneficiation technology with two-stage classification, centrifugal gravity and flotation separation was used to recovery the ultrafine cassiterite. And the good beneficiation indexes of stannum concentrates were obtained with Sn grade of 17.02% and Sn recovery rate of 60.16%, which proved that the beneficiation technology had a good effect on efficient recovery and reuse of the ultrafine cassiterite in tailings.
