Processing of bauxite for smelter grade alumina is quite sensitive to bauxite recovery and total cost for processing of ore, particularly in wet beneficiation. On the other hand, owing to homogeneous nature and consistent quality, some alumina refineries prefer washed ore compared to simple crushed run-of-mine (ROM) bauxite.

The results indicated that the major components of raw sample were diaspore and kaolinite.


The dry low-grade bauxite co-product (tailings) from the separation process would be sold to cement manufacture as an alumina source. Bauxite is commonly added to cement manufacture, and the dry co-product, unlike red mud, does not contain sodium which would prevent its use in cement manufacture.

However, a high-grade bauxite contains up to 60% Al2O3, and many operating bauxite deposits are well below this, occasionally as low as 30-40% Al2O3. Because the desired product is a high purity Al2O3, the remaining oxides in the bauxite (Fe2O3, SiO2, TiO2, Organic material) are separated from the Al2O3 and rejected as alumina refinery resides ...

The bauxite containing less than 50% Al 2 O 3 is called low-grade bauxite ore which is commonly used for the alumina-based abrasives and refractories productions. get price


The bauxite is gibbsitic in nature and amenable to dry and wet beneficiation processes. Similar types of bauxite formed on Kassila series of rocks are being mined and beneficiated at Gondama and Mokanji areas. Bauxite areas are generally buried beneath an over burden of between 1m and 5m of soft soil mixed with lateritic gravel.

What is claimed is: 1. A method for beneficiation of bauxite ore, comprising: providing a source of bauxite ore; drying the bauxite ore to achieve a moisture content of less than about 4.0% by weight, and preferably less than about 2.0% by weight; and separating the bauxite ore with a triboelectric electrostatic belt-type separator or belt separator system (BSS) to generate a …


Low-grade diasporic bauxite was treated with hydrocyclone of small cone-angle.The effects of apex diameter,feed pressure and feed concentration on separation indexes were tested,and then the separation process was discussed by hydrokinetics tentatively.The results show that the increase of apex diameter changes the spacial locality of the envelope of zero vertical velocity, …

Keeping in view the improvement in quality of low-grade materials, beneficiation studies have been carried out at JNARDDC. The studies carried out on laterite (ferruginous, aluminous, siliceous) and low-grade bauxite indicated that the ore can be upgraded with relevance to reduction in iron oxide, silica and enrichment in alumina content.
