摘要: 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。

Abstract: 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 temperature-clean separation with centrifuge replaced the original process of desulphurization-bulk flotation of scheelite and wolframite-separation of scheelite and wolframite by flotation, magnetic separation and gravity separation. In the case of a similar concentrate 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.
