综述了近几年来的一些研究结果:产品比例与经济效益的关系;按锡石嵌布特征分别入磨、细磨、缩小入摇床选的粒级范围,不仅可提高回收率而且可以节能;磁重工艺处理一段床给矿或次精矿,指标优于单一重选;絮凝脱泥是回收细粒、尤其是微细粒锡石的有效途径。
The results of some researches in recent years are summarized as follows: the relationship between the proportion of products and economic benefits; respectively, according to calandia inlaid features into the grinding, fine grinding, narrowing into the rock particle size range, not only can improve the recovery rate and can save energy; Magneto-gravimetric processing of a bed of ore or secondary concentrate, the indicator is better than a single re-election; flocculation desliming is an effective way to recover fine particles, especially fine-grained cassiterite.
