导言近十多年来,对于锡矿石的选矿,<40μm 锡石的浮选,已成为仅次于重选的不可缺少的方法。最初用作浮选锡石的捕收剂的烷基羧酸,终于愈来愈为其他的有效药剂所代替。特别是胂酸和膦酸,以及磺化琥珀酰胺盐具有重要意义。尽管如此,但是有理由要探索对主要参数(矿物共生体,锡石中的杂
Introduction For nearly 10 years, the flotation of <40μm cassiterites has become an indispensable method after re-election for tin ore beneficiation. Alkyl carboxylic acids originally used as collectors for flotation cassiterites are finally being replaced by other effective agents. In particular, arsonic and phosphonic acids, as well as sulfonated succinamide salts, are of great importance. Nevertheless, there are reasons to explore the main parameters (mineral symbiont, cassiterite miscellaneous
