Abstract

The main mechanisms of flotation activation by ions of metals are discussed and critically analyzed. It is shown that ions of metals can be both activators and depressants of flotation. Based on the mechanism of physisorption, it is revealed when metals act as activators and depressants. A method is proposed to stimulate selectivity of extraction of a target mineral in case of undesirable activation of flotation of associate components. The studies can be useful in selection of metal–activator, ratio of concentrations of activator and collector and pH of flotation system.

利用捕收剂的物理吸附机制激发浮选选择性

摘要讨论并认真分析了金属离子激活浮选的主要机制。研究表明，金属离子既可以是浮选的激活剂，也可以是抑制剂。根据物理吸附机理，揭示了金属作为激活剂和抑制剂的作用机理。提出了一种方法，可在伴生组分对浮选产生不良激活作用的情况下，提高目标矿物的提取选择性。这些研究有助于选择金属活化剂、活化剂和捕收剂的浓度比例以及浮选系统的 pH 值。
