六十年代在浮选领域出现了一种新的捕收剂,烷基异羟肟酸(及其盐),经过多年实践,发现异羟肟酸(以下简名羟肟酸),不仅是难选氧化铜矿、赤铁矿、锡石的有效捕收剂,而且对于浮选黑钨矿、钦铁矿、钙钛矿、磷钇矿、烧绿石、据铁矿、独居石、氟碳铈矿等稀有金属矿,也是一种选择性良好的有效捕收剂。 关于羟肟酸(盐)在浮选过程中的作用机理,目前虽然尚未详尽的研究,但在实践上却发展很快,近几年来,国内许多兄弟研 Sixty time in the field of flotation appeared a new collector, alkyl hydroxamic acid (and its salts), after many years of practice, found that hydroxamic acid (hereinafter referred to as hydroxamic acid), not only difficult Copper oxide, perovskite, xenotime, pyrochlore, iron ore, monazite, fluorocarbon Cerium and other rare metals, is also a good selectivity of the effective collector. About hydroxamic acid (salt) in the flotation process mechanism, although not yet exhaustive research, but in practice has developed rapidly, in recent years, many brothers
