地方有色矿山生产的白钨精矿中,主要杂质磷含量较高。含磷矿物又以磷灰石存在。目前大都以盐酸浸取脱除白钨精矿中的磷。白钨矿也属含钙矿物,用盐酸浸取磷灰石对白钨的损失较大。依据白钨矿和磷灰石的比重(5.9～6.2和3.2)差,用摇床分选脱除磷灰石易于分选,采用摇床—酸浸流程,效果可能更好。可先用摇床回收80%的合格产品,20%的不合格产品再用盐酸
In the scheelite concentrate produced by the local non-ferrous mines, the phosphorus content of major impurities is high. Phosphorus minerals and phosphorus in the presence of apatite. Most of the current hydrochloric acid leaching removal of scheelite concentrate of phosphorus. Scheelite is also a calcium mineral, with hydrochloric acid leaching of apatite greater loss of scheelite. According to the difference between scheelite and apatite (5.9-6.2 and 3.2), apatite can be easily separated by shaker separation. The effect of shaker-acid leaching process may be better. Can be shaker recovery of 80% of qualified products, 20% of substandard products and then hydrochloric acid
