意大利一家公司采用了一种铝精矿连续除铜法。该方法利用热的浓硫酸(>93%)与钼精矿混合(重量比1:1),在160～190℃的温度下反应8～10 h,则可溶掉钼精矿中98%以上的铜。除铜是在活塞式流动硫
A company in Italy used a continuous copper removal process for aluminum concentrates. The method utilizes hot concentrated sulfuric acid (> 93%) mixed with molybdenum concentrate (weight ratio of 1: 1) and reacted at a temperature of 160-190 DEG C for 8-10 hours to dissolve more than 98% of the molybdenum concentrate Copper In addition to copper in the piston flow of sulfur
