【摘要】 本文介绍一种不需专用设备、操作简便、行之有效的分选微细矿物方法—重液淘洗法。本法首先用水筛法除去+350目粒级较粗的部分;其后,利用水力分级中沙巴宁法原理,在500ml的烧杯中快速冲洗,除去沉降速度较低的等落粒;最后,将下沉部分烘干,置于淘洗盘中加适量重液,待矿粒润湿后,反复精淘,即可得高纯度精矿物。更多还原

【Abstract】 In this paper, we introduce a sorting microgranular minerals method-heavy liquid elutriation which is easy operation, with high efficiency and without a special equipment. By using this method, at first, we remove relative coarse parts(>350mesh)with the hydraulic classification method, then, wash them rapidly, remove the particles with the low precipitation speed in the beaker 500ml, and then, stove the low precipitation parts, add suitable heavy liquid in the elutriator, elutriate them repeatedly. After Darticlses are wetted. we can get high purificatory minerals.更多还原
