在处理重砂矿物时 ,低品位和有用矿物的较高价值 ,需要较大的处理量和精确的分级和分选技术 ,以便降低单位生产成本。本文描述了新型全流分选机 ,它能够较为经济的完成这些标准。该分选机是结合了上升流和流态化床层技术的二段处理方法 ,它可在一个单独的设备中处理大流量物料。本文报告了煤、铁矿和重矿物的研究工作。
The higher value of low grade and useful minerals in the treatment of heavy sand minerals requires greater throughput and precise classification and sorting techniques in order to reduce unit production costs. This article describes a new full-flow sorter that can accomplish these standards more economically. The separator is a two-stage process combining upflow and fluid bed technologies that handle high-volume materials in a single unit. This paper reports on the research work on coal, iron ore and heavy minerals.
