Products - Bauxite Noranda Bauxite

2021-9-30  The small particle size and low silica content make our Bauxite one of the highest in value worldwide. Refineries that purchase out bauxite can extract high-quality aluminum from Jamaica's bauxite. Our bauxite is also highly sought after in the cement industry due to the high alumina content and the low freight costs.

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 ...

Nature of the Weipa Bauxite deposit, northern Australia

2021-9-8  The extensive bauxite deposits of the Weipa region, northern Queensland, are a loose agglomeration of nodules, pisoliths, ooliths and fine material, with a mean particle size of 5 mm. Only about 5% of the deposit is finer than 0.1 mm, about 5% is coarser than 10 mm, and the bulk of the deposit is made up of pisoliths and ooliths.
