| 摘 要： | 在温湿气候条件下，含多金属硫化物的钨锰－白钨矿矿床会产主一系列的物理、化学变化，形成次生富集钨矿床。通过研究得出，矿石中钨绝大部分是呈离子吸附形式赋存于次生硬锰矿中。矿石中钨品位虽可得到提高，但采用机械选矿方法却难以较好回收。

| Abstract: | Under hygrothermal climate, a series of physicochemical changes take place on huebnerite-scheelite deposit,containing polymetallic sulphi-des and slich a deposit forms a secondary tungsten deposit.It is studied that most of tungsten in ore occurs in secondary psilomelane in the form of adsor-bed ions. Though W grade can be increased, it is difficult to better recover tungsten with mechanical beneficiation methods. |
