Application of Intensifying Secondary Concentration Technology in Reverse Flotation of Bauxite

Abstract:

In order to resolve the problem of fine particle flotation in the reverse flotation of bauxite. a new method of intensifying secondary concentration technology was firstly advanced, and author applied it to ore, achieved eximious experimentation index. 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%.
