The response of diasporic-bauxite flotation to particle ...

2017-8-1  This paper was to investigate the effect of particle size on diasporic-bauxite flotation. For this purpose, concentrate products of various size fractions were collected at different flotation times and forwarded to the testing of Al 2 O 3 and SiO 2 contents. Six flotation kinetic models were applied in the fitting of the experimental data in terms of Al 2 O 3 and SiO 2 recovery.

2015-4-26  The particle size of bauxite residue ranges between 2 and 2000 μm; 80–90 % exists as mud and the remainder is sand. The particle diameter of the sand fraction is almost 20–2000 μm and the particle diameter of the mud fraction is almost less than 20 μm (Table 2) (Nguyen and Boger 1998). Great variation exists in particle size distribution ...

How to Get Aluminum from Bauxite Reduction Process

2021-10-28  The first step of the Bayer process is to use the crushing equipment to crush the bauxite ore into particles with a diameter of about 30 mm. As the particle size becomes smaller, the specific surface area of the bauxite greatly increases, which helps to speed up the follow-up speed of the chemical reaction. Step 2- Washing and separating processes
