浮选是铁精矿提质的最有效的技术和经济解决方案。关于铁矿石浮选的研究始于1931年，证明反阳离子浮选是一种非常有效的氧化铁矿石浮选方法。该方法也可用于降低湿式弱磁选磁铁精矿中的硅含量。综述了几种描述反阳离子浮选法处理铁矿石的研究。着重讨论了矿浆矿物学以及捕收剂和抑制剂的类型和分子结构对浮选的影响。文中还讨论了硅酸盐矿物学在药剂选择和浮选工艺中的作用。铁矿石反阳离子浮选的进一步发展需要更详细地考虑含铁脉石矿物的性质和应用选择性去除这些物质的原始方法。(C)2014爱思唯尔有限公司版权所有。
Flotation is the most effective solution, both technologically and economically, when upgrading iron concentrates. Research regarding iron ore flotation began in 1931, demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores. This method can also be applied to reduce the silica content in magnetite concentrates obtained using wet low-intensity magnetic separation. Several studies describing the processing of iron ores via reverse cationic flotation are reviewed. The predominate role of the pulp mineralogy, as well as the type and molecular structures of the collectors and depressants, on flotation is discussed critically. The results concerning the role of the silicate mineralogy on the choice of reagents and flotation processes are also discussed. Further development of the reverse cationic flotation of iron ores requires a more detailed consideration of the nature of iron-bearing gangue minerals and the application of original approaches for the selective removal of these species.
