Separation of diaspore from bauxite by selective

25/04/2014 Selective flocculation is a new method to solve the problem of China’s bauxite de-silication besides flotation and reverse flotation. The method of selective flocculation of bauxite using hydrolyzed polyacrylamide as flocculant was experimented and evaluated. The results of diaspore and kaolinite single mineral settling tests show that the difference between settlement yield of kaolinite

A review of pretreatment of diasporic bauxite ores by

01/12/2017 As it was noted, diasporic bauxite ores (diaspore is naturally hydrophilic) have a low Al/Si mass ratio, and an extensive comminution has to be performed on the ore in order to liberate value and gangue minerals and prepare them for selective interaction with reagents (direct and reverse flotation) (Wen-li et al., 2014, Kurusu et al., 2009).

Reverse flotation for removal of silicates from diasporic

Abstract Aluminum-silicates such as pyrophyllite, illite, kaolinite and chlorite are impurity minerals in diasporic-bauxite, it being necessary to remove these silicate minerals to improve the mass ratio of Al2O3/SiO2 of diasporic-bauxite for the Bayer process. A new quaternary ammonium salt (DTAL) has been shown to be efficient in the flotation of these silicates.
