摘　　要：本文介绍了针对某选矿厂Φ15 m浓密机沉砂中的微细泥锡石,通过试验研究探索高效、低成本的微细粒锡石回收工艺,通过多种试验方案比较,确定采用摇床回收微细粒锡石,可以获得锡粗精矿含锡6.20%,回收率达58.58%的选矿指标,对该选矿厂解决微细粒锡石难回收提供有效的回收方法,同时对同类选矿厂尾矿中微细粒级锡石的回收工艺有所借鉴。Directed at the ultrafine cassiterite from underflow ~15 m thickener in a concentrator,through experimen- tal study, high efficient and low cost of cassiterite recovery process was explored. By comparing different kinds of test schemes, the process of tabling was adopted, which can obtain the tin roughing concentrate with the tin of 6.20% and recovery rate of 58.58%, which provides efficient way for the recovery of cassiterite in the concentrator. Also, it provides references for the similar concentrator for the recovery of ultrafine cassiterite.
