大吉山钨矿选矿厂针对-60目精选流程尾矿品位较高(WO_3l-2.8%)的情况,改扫选摇床中矿为扫选摇床尾矿,取得较好的效果。该厂-60目钨精选流程为浮选-重选流程。重选部分为:粗选尾矿进浓密机,沉砂与粗选中矿入分级斗,其沉砂进入一次扫选,得精矿,中矿与尾矿进行二次扫选,得精矿和尾矿,中矿返回分级斗。该流程在生产中尽管精工细作,尾矿品位WO_3仍达1-2.8%。为此,1975年对流程进行了改进。将二次扫选中矿与尾矿改为二次扫选尾矿,其中矿与一次
The Dajishan Tungsten Concentrate Dressing Plant Aiming at the situation that the tailings grade in the -60 mesh selection process is high (WO_3l-2.8%), the ore in the shaker is changed to sweep the tailings of the shaker, thus obtaining better results. The plant -60 mesh tungsten selection process flotation - re-election process. The reelection part is as follows: rougher tailings into the thickener, grit and crude ore into the classification bucket, the grit into a sweep, concentrate, ore and tailings for the second sweep, concentrate and Tailings, mining return classification bucket. Although the process in the production of Seiko secret agents, tailings grade WO_3 still reached 1-2.8%. To this end, the process was improved in 1975. The second sweep of mine and tailings to the second sweep tailings, including mine and once
