摘要
我国拥有菱镁矿资源优势,但长期的开采导致优质菱镁矿不断减少,对低品位菱镁矿的利用率不高。白云石是菱镁矿提质降杂过程中需要脱除的含钙杂质,与菱镁矿有着相似的结构及浮选特性,二者的分离成为技术难题。本文综述了近年来对菱镁矿和白云石浮选分离影响因素的研究成果,以及浮选工艺的研究和应用进展,探讨了未来发展方向。
There are rich resources of magnesite in China,but the high quality magnesite resources are reducing due to long-term excessive mining and the utilization rate of low quality magnesite ore is very low.Dolomite is calcium-bearing mineral which should be removed in quality improvement and impurity reduction process of magnesit.Separation of dolomite from magnesite is difficult because dolomite and magnesite are similar in crystal structure and flotation characteristic.In this article,the factors affected the flotation separation of dolomite from magnesite and the research and application status are briefly reviewed,the future direction of development is presented.
