摘要
硅是铁矿石中一种典型的有害杂质,降低铁精矿中硅含量一直是铁矿石分选的重要课题。对铁矿石脱硅工艺与浮选药剂制度的研究进展做了系统的综述,重点介绍了浮选脱硅的研究现状和发展趋势。文中指出含硅铁矿石钙离子活化—阴离子反浮选工艺具有广阔的应用前景,进一步提高浮选药剂的选择性和适应性具有重要的现实意义。
Silicon is a typical harmful impurity in iron ore.,So reducing the content of silicon in iron concentrate is always an important topic in iron ore separation.This paper systematically summarizes the research progress of iron ore desilication technology and flotation reagent regime.The research status and development trend of flotation desilication are introduced emphatically.It points out that calcium ion activation-anion reverse flotation of iron ore containing silicon has broad application prospects and how to further improve the selectivity and adaptability of reagents is of great practical significance to the process.
