摘要:
金属离子在金红石的浮选过程扮演着重要角色，主要分为活化和抑制，活化离子有Pb2+、Bi3+和Cu2+，抑制离子有Al3+、Fe3+，其中的作用机理表现出明显不同。本文综述了近年来金红石常用的浮选捕收剂，重点介绍了金红石浮选中活化金属离子Pb2+、Bi3+、Cu2+和抑制金属离子Al3+、Fe3+对其浮选的影响及作用机理，为了解金红石浮选中常见金属离子影响及作用机理提供参考。
Abstract:Metal ions play an important role in rutile flotation, which can be divided into activation and inhibition. The activation ions include Pb2+, Bi3+ and Cu2+, and the inhibition ions include Al3+ and Fe3+. Their mechanism of action is obviously different. In this paper, the commonly used flotation collectors of rutile in recent years are summarized, and the influence and action mechanism of activation ions Pb2+, Bi3+, Cu2+ and inhibition ions Al3+, Fe3+ on rutile flotation are mainly introduced, so as to provide reference for understanding the influence and action mechanism of common metal ions in rutile flotation.

Table 1. Mechanism of activation and inhibition of metal ions
作用 离子 作用机理 活化 Pb2+ 1. Pb(OH)+、Pb(OH)2(s)与 Ti-OH生成Ti-O-Pb+，增加活化位点
2. Pb2+与BHA生成Pb-BHA复合物，大量吸附金红石，活化浮选Bi3+ Bi3+占据原始Ca2+的位阻位置生成 (Bi(OH)n+(3-n))，进而与Ti-OH发生反成表面络合物Ti-O-Bi2+，增加金红石表面的活化位点 Cu2+ Cu2+与Fe2+反应生成Fe3+和Cu+，随后Cu(II)和Cu(I)与捕收剂HPA[P3+] 反应生成Cu(I)HPA[P3+]和Cu+HPA[P3+]，HPA疏水基朝外，从而活化浮选 Al3+ 1. Al(OH)3沉淀覆盖在金红石表面，阻止捕收剂的作用
2. Al(OH)3沉淀物在金红石表面架桥形成Ti-O-Al键，掩盖活化位点抑制 Fe3+ 1. Fe(OH)3沉淀物物理吸附在金红石表面，导致其表面亲水
2. Fe3+离子与捕收剂形成络合物，消耗捕收剂
