摘要

江西某大型钨矿,日产细泥400~500 t,含WO30.13%~0.5%,-0.074mm含量大于90%,-0.02mm含量达32.3%。采用重选预富集-浮选-重选选矿新工艺选别该细泥,小型试验指标为:总钨精矿品位WO345.26%,回收率62.33%,其中白钨精矿品位WO355.38%,回收率29.82%,黑钨精矿品位WO338.76%,回收率32.51%。工业试验指标为:总钨精矿品位WO351.148%,回收率62.52%,其中白钨精矿品位WO365.43%,回收率31.40%,黑钨精矿品位WO341.90%,回收率31.12%。
        There can be 400~500t tungsten slimes containing 0.13%~0.5%WO3 daily produced from a large-scale tungsten mine in Jiangxi Province,among them the content of-0.074mm is >90%,and the content of-0.02mm reached 32%.A new technology of "gravity pre-concentration-flotation-gravity separation" is adopted for separating these kinds of tungsten slimes.The bench test results show that the grade of total tungsten concentrate is 45.26%WO3,the recovery is 62.33%,among which the grade of scheelite concentrate is 55.38%WO3,the recovery is 29.82%,and the grade of wolframite concentrate is 38.76%WO3,the recovery is 32.51%.The commercial-scale trail results show that the grade of total tungsten concentrate is 51.148%WO3,the recovery is 62.52%,among which the grade of scheelite concentrate is 65.43%WO3,the recovery is 31.40%,and the grade of wolframite concentrate is 41.90% WO3,the recovery is 31.12%.
