研究了用十二烷三甲溴化铵浮选分离细柱石英(-10微米)和细粒赤铁矿(-10微米)的混合物(重量比1:1)的过程。测定了石英和赤铁矿悬浮液的絮凝和分散过程的参数。从多絮凝的观点分析了浮选结果。研究证明,在酸性溶液(pH=5)中石英带负电荷,而赤铁矿带正电荷,由于这种矿物颗粒有絮凝作用,混合物难以分离。在碱性溶 The process of separating a mixture of fine column quartz (-10 micrometers) and fine hematite (-10 micrometers) (weight ratio 1: 1) with flotation with dodecane trimethylammonium bromide was studied. The parameters of flocculation and dispersion of quartz and hematite suspensions were determined. The flotation results were analyzed from the point of view of multi-flocculation. Studies have shown that quartz is negatively charged in an acidic solution (pH = 5), while the hematite zone is positively charged. Because of the flocculation of such mineral particles, the mixture is difficult to separate. In alkaline solution
