The paper presents results of the study on recovery of fine bauxite ore particles -1 mm from tailings of the Tan Rai - Lam Dong bauxite mineral processing plant by the use of mechanical classifiers.

Bauxite can be found in a number of different physical forms including: pisolitic, friable and hardcap. Each bauxite will have its own distinctive crushing and milling characteristics. Bauxite can be highly variable through the mine pit profile, both vertically and horizontally. Often large blocks from blasted or ripped bauxite can be upto 1±2 m 3

The first step in producing aluminium is mining this ore. Bauxite occurs mainly in tropical and sub-tropical areas, like Africa, the Caribbean, South America and Australia. Australia is one of the world's largest producers of bauxite, with five large mines supplying around 30 per cent of global production. Bauxite mining has five steps:

Four tonnes of bauxite are usually required in order to generate two tonnes of finished alumina which ultimately produces approximately one tonne of aluminium at the primary smelter. 2. Bauxite feed hopper. 3. Mechanical crusher employed to reduce bauxite particle size and increase surface area for chemical extraction. 4.

Bauxite ore grinding is the important beneficiation operations at bauxite mines used for particle size reduction for separation of mineral and waste.At the bauxite beneficiation plant, the raw bauxite ore will be fed into primary crusher for primary crushing. After the crushing process, the bauxite is screened and washed to remove fine particles.

A cross-sectional study of employees at a US bauxite mine, alumina refinery, and alumina-based chemical products plant studied lung function in relation to cumulative total dust exposures.18 The subjects were employed at some time between 1975 and 1981. Because one third of the study cohort never smoked, the effects of dust exposure could …
