钨钢含锡高会降低钢的切削性能。因此,降低钨精矿含锡是钨精选的一项重要任务。多年来,我厂采用磁选—氯化焙烧工艺降低细泥精矿和重杂精矿中的锡,起了一定的作用。但氯化焙烧存在操作条件差,金属损失大,能耗多,环境污染严重等问题。针对这一情况,1983年我厂与广州有色金属研 High tungsten steel containing tungsten will reduce the cutting performance of steel. Therefore, the reduction of tungsten concentrates containing tin is an important task of tungsten selection. Over the years, I plant using magnetic separation - chlorination roasting process to reduce fine mud concentrate and heavy impurities in the tin, played a certain role. However, chlorination roasting has the problems of poor operating conditions, large metal loss, high energy consumption and serious environmental pollution. In response to this situation, I plant in 1983 and non-ferrous metals research in Guangzhou
