中文摘要

选择性抑制剂可实现低碱度铜硫浮选分离。在铜硫矿物浮选体系中，抑制剂通常优先与黄铁矿表面发生相互作用，促使矿物表面亲水，阻碍捕收剂的吸附。本文综述了低碱度铜硫浮选分离抑制剂的研究进展，分别对无机抑制剂和有机抑制剂的应用和抑制机理进行了归纳总结。其中，无机抑制剂包括氧化剂和硫氧化合物，有机抑制剂包括天然多糖(淀粉、糊精、魔芋葡甘聚糖和半乳甘露聚糖)、改性聚合物(羧甲基纤维素、聚丙烯酰胺、木质素磺酸盐和三羧酸钠淀粉)、有机酸(聚谷氨酸、腐殖酸钠、单宁酸、焦没食子酸、水杨酸和乳酸)、二甲基二硫代氨基甲酸钠和二乙烯三胺。在总结了不同类型抑制剂作用特点的基础上，本文对无机抑制剂和有机抑制剂在低碱度铜硫浮选分离中的应用前景进行了评述。此外，本文系统地介绍了不同类型有机抑制剂在矿物表面的抑制机制差异。最后，针对现有研究的不足对低碱度铜硫浮选分离抑制剂的未来研究方向提出了建议。

Advances in depressants for flotation separation of Cu–Fe sulfide minerals at low alkalinity: A critical review

+ Author Affiliations

Abstract

Abstract

The flotation separation of Cu–Fe sulfide minerals at low alkalinity can be achieved using selective depressants. In the flotation system of Cu–Fe sulfide minerals, depressants usually preferentially interact with the pyrite surface to render the mineral surface hydrophilic and hinder the adsorption of the collector. This review summarizes the advances in depressants for the flotation separation of Cu–Fe sulfide minerals at low alkalinity. These advances include use of inorganic depressants (oxidants and sulfur–oxygen compounds), natural polysaccharides (starch, dextrin, konjac glucomannan, and galactomannan), modified polymers (carboxymethyl cellulose, polyacrylamide, lignosulfonate, and tricarboxylate sodium starch), organic acids (polyglutamic acid, sodium humate, tannic acid, pyrogallic acid, salicylic acid, and lactic acid), sodium dimethyl dithiocarbamate, and diethylenetriamine. The potential application of specific inorganic and organic depressants in the flotation separation of Cu–Fe sulfide minerals at low alkalinity is reviewed. The advances in the use of organic depressants with respect to the flotation separation of Cu–Fe sulfide minerals are comprehensively detailed. Additionally, the depression performances and mechanisms of different types of organic depressants on mineral surfaces are summarized. Finally, several perspectives on depressants vis-à-vis flotation separation of Cu–Fe sulfide minerals at low alkalinity are proposed.
- Cu–Fe sulfide minerals;
- flotation separation;
- selective depressants;
- depression mechanism
