bauxite ore is concentrated by magnetic separation

Dry Magnetic Separation of Bauxite Ore
2012-12-13 · Dry Magnetic Separation of Bauxite Ore R.P. Bhagat, B. Banerjee , P. Saha and B.C. Mukherjee National Metallurgical Laboratory, Jamshedpur 831 007. Email : [email protected] Abstract The paper describes the beneficiation results of the bauxite ore from Durgamanwadi mines to achieve a grade of the products conforming to refractory specification.
Details
Which process is used for the concentration of Bauxite ...
The ore which can be attracted by the magnetic field can be concentrated by the process of magnetic separation. Among the ores mentioned in table 6.1, the ores of iron such as haematite (Fe 2 O 3), magnetite (Fe 3 O 4), siderite (FeCO 3), and iron pyrites (FeS 2) can be separated by the process of magnetic separation.

Bauxite is concentrated by: | Chemistry Questions
The bauxite is purified by the Bayer Process. First the ore is mixed with a hot concentrated solution of sodium hydroxide. The N a O H will dissolve the oxides of aluminum and silicon but not other impurities such as iron oxides, which remains insoluble. The insoluble materials are removed by filtration.This method is called the chemical method.
