钛铁矿浮选药剂及微波预处理改善其浮选指标的研究进展

我国钛资源钛品位低、性质复杂，浮选是富集钛铁矿最有效的方法。从捕收剂、活化剂、抑制剂角度综述了钛铁矿浮选药剂的研究进展。综述了钛铁矿表面性质与其可浮性的关系及微波表面预处理提高钛铁矿可浮性的研究进展。钛铁矿浮选时捕收剂主要通过化学吸附方式作用在矿物表面，捕收剂组合使用较单一捕收剂对钛铁矿的浮选指标好；在钛铁矿浮选抑制剂方面，铅离子活化的报道较多，铜离子活化、硫酸活化等也逐渐被报道；微波用于钛铁矿表面预处理，降低了捕收剂、抑制剂、活化剂等浮选药剂的消耗量，具有较好的运用前景。今后，钛铁矿浮选技术发展的主要方向仍然是开发新型、环保、低成本、高效的浮选药剂。

Research Progress of Ilmenite Flotation Reagents and Microwave Pretreatment Improve Flotation Index

Flotation is the most effective method for the enrichment of ilmenite due to the low grade and complex properties of titanium resources in China. The research progress of ilmenite flotation agents was reviewed from the perspectives of collector， activator and inhibitor. The relationship between the surface properties of ilmenite minerals and it’s floatability and the research progress of microwave surface pretreatment to improve the floatability of ilmenite are reviewed. In the flotation of ilmenite， the collector mainly functions on the mineral surface by means of chemical adsorption. The collectors combination use will have good flotation index than using single flotation reagents. In ilmenite flotation inhibitors， there are many reports on the activation of lead ions， copper ions and sulfuric acid， etc. also reported in recent years. Microwave is applied to the surface pretreatment of ilmenite， which reduces the consumption of collector， inhibitor， activator and other flotation agents. In the future， the main direction of ilmenite flotation technology development is still to develop new， environmentally friendly， low-cost and efficient flotation agents.
