细粒锡石的浮选还只有10～12年的工业实践。早期所知的捕收剂对锡石的选择性差,选出的锡精矿达不到工业回收的要求,有效捕收剂的选择也受到限制。我们建立浮选系统时,不仅要用有效的捕收剂,而且也需要用具有选择性的脉石抑制剂或分散剂,以达到满意的选择性和回收率。为寻求选择
Fine flotation of cassiterite only 10 to 12 years of industrial practice. The earlier known collectors have poor selectivity for cassiterite and the selected tin concentrates do not meet the requirements for industrial recovery, and the choice of an effective collector is also limited. When we set up a flotation system, we not only use effective collectors, but also selective gangue inhibitors or dispersants to achieve satisfactory selectivity and recovery. To seek for choice
