摘要:
我国钛铁矿资源总量庞大，随着钛铁矿矿石性质的变化，钛铁矿矿石选矿难度增加，传统的浮选药剂已不能满足生产要求。近些年来的研究大多致力于传统药剂的组合和浮选新药剂的研发。传统单一类捕收剂浮选效果不显著，组合捕收剂的开发使用成为研究方向。抑制剂是通过降低矿物表面电位来减弱矿物间异相凝聚作用，以及选择性吸附于脉石矿物表面从而阻碍捕收剂的吸附。活化剂是通过提高钛铁矿表面活性位点或组分的相对含量而起到活化作用。主要综述了脂肪酸、膦酸、胂酸和羟肟酸类等捕收剂，水玻璃、草酸、羧甲基纤维素等抑制剂和铅离子、铜离子以及硫酸等活化剂。运用XPS、FTIR和DFT等检测分析手段，可研究官能团在矿物表面的作用方式，为新型药剂的研发和优化指明方向。
Abstract:The total amount of ilmenite resources is huge in China. With the change of ilmenite ore properties, the difficulty of ilmenite ore dressing increases, and the traditional flotation agents can no longer meet the production requirements. In recent years, most of the researches focus on the combination of traditional agents and the development of new agents for flotation. The flotation effect of the traditional single collector is not significant, so the development and application of the combined collector has become the research direction. The depressant is to reduce the potential of mineral surface to reduce the heterogeneous condensation between minerals, and selectively adsorb on the surface of gangue minerals, thus hindering the adsorption of collectors. Activators are activated by increasing the relative content of active sites or components on the surface of ilmenite. This paper mainly reviews the collectors of fatty acids, phosphonic acids, arsonic acids and hydroxamic acids, depressants of sodium silicate, oxalic acid, carboxymethyl cellulose and activators of lead ions, copper ions and sulfuric acid. By means of XPS, FTIR, DFT and other detection and analysis methods, the action modes of functional groups on mineral surface can be studied, which can point out the direction for the development and optimization of new agents.
