钨矿精选过程中产生的中矿和尾矿含有Ag、Bi、Pb、W、Cu等多种金属和大量的黄铁矿。用FeCl_3溶液浸出可使Ag、Bi、Pb等金属大部分溶解,然后从溶液中回收(如用铁屑置换或结晶法)。浸出渣中的其他有价成分可用选-冶联合流程回收。该法经济效益明显,污染问题易解决。唯设备防腐问题尚待解决。 Mines and tailings produced during the tungsten ore beneficiation process contain various metals such as Ag, Bi, Pb, W, Cu and a large amount of pyrite. Leaching with FeCl_3 solution can dissolve Ag, Bi, Pb and other metals mostly, and then recover from the solution (such as iron scrap replacement or crystallization). Leaching residue in the other valuable components available election - Ye joint recovery process. The law obvious economic benefits, pollution problems easy to solve. The only equipment corrosion problem to be solved.
