| 摘 要： | 在用碱法生产氧化铝的过程中,硅是铝土矿中最有害的杂质。本文系统评述了铝土矿选矿脱硅的不同方法,重点介绍了用浮选法进行铝土矿选矿脱硅的基本原理、研究现状及其应用进展。铝土矿正浮选脱硅法已获得工业应用,反浮选脱硅法是一种前景较好的浮选脱硅法,但还存在一定难度,需要开展系统深入的研究工作。

| Abstract: | For production of alumina by alkaline process,silicon in bauxite is the most harmful impurity.In this paper,different methods for bauxite desilication are systematically commented upon.The emphasis is laid on the principle of bauxite desilication by flotation process,and present situation and progression of its research.The positive flotation desilication has been put into industrial service.The reverse flotation is a perspective way for bauxite desilication but it is confronted with some difficulties,which needs to be studied systematically and further. |
