首先用活化剂(例如C_(1-30)的羧酸或羧酸盐)活化锡石,然后用一种含P或含As的捕收剂、一种胺类捕收剂或者C_(82-20)的脂肪酸捕收剂进行浮选。于是,锡石(80％通过50微米)用醋酸铅活化,使用Aeropromoter845捕 The cassiterite is first activated with an activator such as a carboxylic acid or carboxylate of C 1- (1-30) and then treated with a P or As-containing collector, an amine collector or C 82- 20) fatty acid collector flotation. Cassiterite (80% through 50 microns) was then activated with lead acetate using an Aeropromoter 845 trap
