随着铝工业的高速发展和优质铝土矿资源的枯竭,铝土矿选矿已引起世界各国的广泛关注,所以应用经济合理的选矿方法来提高铝土矿品位,降低铝土矿中的有害二氧化硅是行之有效的。铝土矿正浮选脱硅技术已经在部分企业中得到应用,虽然多项技术成果达到了国际领先水平,但仍然存在一些问题。通过关键技术问题的解决,达到提高资源利用率和企业经济效益,对于提高我国铝工业在国际市场的竞争能力,实现我国铝工业的可持续发展具有重要的意义。
With the rapid development of the aluminum industry and the depletion of high-quality bauxite resources, beneficiation of bauxite has drawn wide attention in various countries of the world. Therefore, it is necessary to apply economical and reasonable beneficiation methods to increase the grade of bauxite and reduce the harmful contents of bauxite Silica is effective. Bauxite flotation desiliconization technology has been applied in some enterprises, although a number of technical achievements reached the international advanced level, but there are still some problems. Through the solution of key technical problems, it is of great significance to improve the utilization rate of resources and the economic benefits of enterprises in order to enhance the competitiveness of China’s aluminum industry in the international market and realize the sustainable development of China’s aluminum industry.
