我矿香花铺选厂处理矿石为萤石交代岩型白钨矿石。采用重-浮联合流程,生产一级一类白钨精矿,诸元素的含量是(%):WO_365~66.50、S0.23~0.31、As0.076、Pb0.17、Zn0.03~0.04、Sn0.12~0.18、P0.003、Mo0.004~0.007、Cu0.0075~0.009、SiO_20.9~1.24、Bi0.01。为适应外贸需要,我矿于1981年5~9月进行了白钨粗精矿浮选特级白钨精矿试验。试验表明,采用预先脱硫,浮选白钨,精矿酸浸流程,可获得回收率为86.30%的特级白钨精矿,达到我国外贸特级品标准。在钨精选作业中,采用全部中矿集中加水玻
Mine ore processing plant for dressing shop for fluorite rock type scheelite ore. The heavy-float combined process is used to produce a class I scheelite concentrate. The contents of the elements are (%): WO_365~66.50, S0.23~0.31, As0.076, Pb0.17, Zn0.03~0.04, Sn0.12-0.18, P.003, Mo0.004-0.007, Cu0.0075-0.009, SiO20.9-1.24, Bi0.01. In order to meet the needs of foreign trade, our mine conducted the scheelite concentrate levitation white tungsten concentrate test from May to September 1981. Tests show that the use of pre-desulfurization, flotation of scheelite, concentrate acid leaching process, we can get a recovery rate of 86.30% special grade scheelite concentrate, to reach China’s foreign trade special grade standards. Tungsten in the selection of operations, using all concentrated in the mine with water glass
