为了在一定程度上缓解世界矿物加工工业普遍面临的环境和能源问题,矿石预选已愈来愈多地引起各国选矿界的重视。重介质分选,在大多数情况下被用作预选的手段之一。在某些情况下,特别是选煤,也可以作为主要的选别手段。 重介质分选的主要特点是: 1.流程中无污水排出; 2.矿石在细磨前即可先产出部分粗粒精矿,以减少后续作业的处理量及处理费用; 3.从理论上讲,它可以处理小至0.1毫米的粒级,能适应很宽的粒度范围;
In order to alleviate to a certain extent the environment and energy problems that the world mineral processing industry generally faces, ore preselection has drawn increasing attention from the dressing industry in various countries. Heavy media sorting is used as a preselection tool in most cases. In some cases, especially coal preparation, it can also be used as a major sorting out mechanism. The main features of heavy media sorting are: 1. No effluent discharge in the process; 2. The ore can be produced before the fine grinding part of the coarse ore concentrate, in order to reduce the follow-up of the handling capacity and processing costs; 3. From the theory On the speaking, it can handle the grain size as small as 0.1 mm, can adapt to a wide range of particle size;
