概述了国内外高硅铝土矿的脱硅选矿现状，对目前采用的各种物理选矿方法和化学选矿方法，进行了简要的技术经济分析。在分析铝土矿的矿物结构的基础上，紧密结合现有的氧化铝工艺生产流程，提出化学物理选矿方法，该方法工艺简单，成本低，通过进一步试验研究，可望迅速用于我国的氧化铝工业。
The current status of desiliconization beneficiation of high silica bauxite at home and abroad is summarized. A brief technical and economic analysis is made on various physical beneficiation methods and chemical beneficiation methods currently used. Based on the analysis of the mineral structure of the bauxite, the chemical and physical beneficiation method is put forward in close connection with the existing alumina production process. The method is simple in process and low in cost and can be rapidly applied to the oxidation of our country through further experimental studies Aluminum industry.
