一种新的氟碳酸盐稀土矿物二元羧酸捕收剂(804~#)成功地应用于两个选矿流程。与其他稀土矿物的捕收剂比较,它的特点是价格低,并具有良好的选别效果。本文对804~#和油酸与RE~(3+)、Fe~(3+)、Ba~(2+)、Ca~(2+)等离子的反应特征作了比较,并对其良好的选别效果作了初步分析。 A new fluorocarbon rare earth mineral dicarboxylic acid collector (804 ~ #) was successfully applied to two beneficiation processes. Compared with other rare earth mineral collectors, it is characterized by low price and good sorting effect. In this paper, the reaction characteristics of 804 ~ # and oleic acid with RE ~ (3 +), Fe ~ (3 +), Ba ~ (2 +) and Ca ~ (2+) No effect made a preliminary analysis.
