Application of Intensifying Secondary Concentration ...

The reverse flotation tests of intensifying secondary concentration aiming at bauxite from Guizhou province were studied. The results show that diaspore concentrate directly used in the Bayer-mineral processing method can be obtained by using the intensifying secondary concentration technology without pre—desliming. The average A/S of the concentrate is 10.28 with a recovery rate of 85.41%.

Bauxite is concentrated by: - Toppr Ask

The bauxite is purified by the Bayer Process. First the ore is mixed with a hot concentrated solution of sodium hydroxide. The N aOH 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.
