《提高大吉山钨矿钨细泥回收率的试验研究》系中国有色金属工业总公司和中国华兴钨业公司于1984年先后下达给赣州有色冶金研究所和大吉山钨矿的科研项目,从小型试验到工业试验完成,前后经过了六年时间,参加试验的人员达30余人。小型试验进行了重—磁—重—浮与刻槽弹簧摇床加振摆皮带溜槽的单一重选等多方案比较试验,获得特级Ⅰ类1号黑钨精矿和一级Ⅰ、Ⅱ、Ⅲ号白钨精矿及含WO_3为25％以上的甲级钨细泥精矿,钨回收率达51.68％至60.05％,达到或超过了上级下达的各项试验指标,分别于1984年11月和12月提交了《提高大吉山钨矿细泥回收率的试验研究报告》及其补充资 “Experimental Research on Improving Recovery Rate of Tungsten Fine Slime in Dajishan Tungsten Mine” China Nonferrous Metals Industry Corporation and Huaxing Tungsten Company of China successively issued scientific research projects to Ganzhou Institute of Nonferrous Metallurgy and Dajishan Tungsten Mine in 1984, After the test was completed in the industrial test, it took six years before and after the experiment to reach more than 30 personnel. The small scale experiments were carried out in various programs such as heavy-magnetic-heavy-floatation and single-selection comparison with grooved spring shaker vibration chute belt chute to obtain the special grade Ⅰ class 1 wolframite concentrate and grade Ⅰ, Ⅱ, Ⅲ White scheelite concentrate and Grade A tungsten fine ore concentrate containing WO_3 of 25% or more, the recovery rate of tungsten reached 51.68% to 60.05%, meeting or exceeding the test targets issued by superiors, respectively, in November 1984 and December submitted “to improve the test of recovery of fine mud in the Dajishan tungsten ore research report” and its supplementary funding
