用离心分离机对细粒和中粒方铅矿的粗聚合体从空气-溶液相间界面脱落的临界力进行了研究。用乙基黄原酸钾捕收剂对粒度为-10微米和+40-125微米的方铅矿作了试验。试验证明,细粒方铅矿聚合体在相间界面上的固着力低于中粒聚合体的固着力。研
The critical force for the detachment of coarse aggregates of fine-grained galena from the air-solution interface was studied by centrifugal separator. Galena with particle sizes of -10 microns and + 40-125 microns were tested with potassium ethylxanthate collector. Experiments have shown that the adhesion of fine galena aggregates at the interphase interface is lower than that of the medium aggregates. research
