由于铜的销售跌落,钼却畅销于市场,因此,一些大的铜选厂的管理部门密切注重改善辉钼矿的回收。许多选矿厂仅在粗磨回路添加油类捕收剂就改善了粗粒辉铝矿的回收。而过去,这些厂都拒绝这样做,因其对铜的回收率或铜精矿品位有影响。由于副产品钼的销售价格(4.41美元),超过主产品市价,就试图少回收一点铜而回收更多的辉钼矿。按铜回收率为85％,每磅铜为0.64美元,钼的总回收率为50％,目前销售价格每磅钼为4.41美元计算,在某种矿
As sales of copper drop, molybdenum is sold well in the market, so the management of some large copper processing plants pay close attention to the improvement of molybdenum recovery. Many concentrators only improve the recovery of coarse grained bauxite by adding an oil collector to the roughing circuit. In the past, these plants refused to do so because of their impact on copper recovery or copper concentrate grade. As the by-product molybdenum sales price ($ 4.41) exceeded the market price of the main product, it tried to recover a little less copper to recover more molybdenite. The copper recovery rate of 85%, 0.64 US dollars per pound of copper, the total molybdenum recovery rate of 50%, the current sales price of 4.41 US dollars per pound of molybdenum calculated in a mine
