为了试制优质白钨精矿,提高它在国际市场上的竞争能力,最近我所对柿竹园多金属矿试选厂所产白钨精矿进行了研究。目的是除提高主成分外,还着重降低精矿中的杂质含量,以达到冶金部提出的高质量白钨精矿的要求。锰在白钨精矿中要求控制在0.05％以下,是研究的主要对象之一。试验所取的物料,含WO_373.40—76.59％,Bi0.019—0.023％,S0.039—0.045％,Mn0.122—0.16％,其粒度小于
In order to trial high-quality scheelite concentrate and improve its competitiveness in the international market, I recently conducted a study on scheelite produced by the trial plant of Shizhuyuan polymetallic ore. The purpose is to increase the main components, but also focus on reducing the impurity content of the concentrate, in order to achieve the Ministry of Metallurgical proposed high-quality scheelite requirements. The requirement of manganese in scheelite to be controlled below 0.05% is one of the main research subjects. Test the material taken, containing WO_373.40-76.59%, Bi0.019-0.023%, S0.039-0.045%, Mn0.122-0.16%, the particle size is less than
