宁化行洛坑钨矿选矿厂针对其钨细泥处理系统生产成本高,钨回收难度大,经济效益差的状况,采用脱泥-脱硫-常温浮选-离心选矿机精选新工艺取代原有脱硫-黑白钨混合浮选-浮、磁、重选黑白钨分离复杂工艺,在精矿品位相近的情况下,使系统作业回收率和对原矿回收率分别提高了43.91和6.91个百分点,同时使精矿药剂成本和电费减少了69.51%,较成功地解决了钨细泥回收的技术难题.%Due to higher costs at and more difficulty in tungsten slime recovery in Ninghua Xingluokeng Tungsten dressing plant with lower economic benefit, the new process of desliming-desulphurization-flotation in normal temperatureclean separation with centrifuge replaced the original process of desulphurization-bulk flotation of seheelite and wolframiteseparation of scheelite and wofframite by flotation, magnetic separation and gravity separation. In the case of a similar coneentrate grade, the new process improved the system operation recovery and recovery of raw ores by 43.91％ and 6. 91％respectively and decreased the costs at agents and electric power by 69.51％, which successfully resolved the technical difficulties in tungsten slime recovery.
