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 (ARR) or red mud. In general, the lower quality the bauxite (ie lower Al2O3 content) the more red mud is generated per ton of alumina product.

After separating, the parts that can meet standard will be transferred away as final products, while the other parts will be returned to impact crusher, thus forming a closed circuit. Size of final products can be combined and graded according to your specific requirement.
Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite. The aluminum is precipitated out of solution in the form of aluminum hydroxide ...
The Bayer process is the principal method for the production of alumina from bauxite worldwide. The modern version of the process (developed in the 1880's) still maintains the key steps of dissolution of alumina-rich minerals into hot caustic solution, separation of the insoluble phases, followed by gibbsite precipitation and calcination of …

There has been a case report of mild pulmonary fibrosis—occurring in a man exposed to bauxite crushing and transport from 1936 to 1962. 17 The incidental finding on autopsy led to confirmation of the presence of bauxite within the area of fibrosis. More recently, epidemiological studies of employees exposed to bauxite dust have been conducted.
Fig. 1 : Main alumina refinery processes: Bayer process and calcination (Image courtesy of Mytilineos SA) The Bayer process typically consists of the following stages: Preparation of bauxite (bauxite crushing & grinding) Digestion under pressure (leaching) Solid-liquid separation. Precipitation and crystallisation of aluminium hydroxide.
The bauxite is then transported to the crushing and washing area, reducing the particle size and increasing the available surface area for the digestion stage. The material that is discharged from the mill is called slurry ... Alumina is formed into a white powder, this is the final product of the Bayer Process, ready for shipment to aluminum ...

Maintenance Costs. The cost of maintaining a bauxite calcination crusher can vary depending on the size and complexity of the crusher. However, in general, maintenance costs can be expected to represent a significant portion of the overall operating costs of a bauxite calcination plant. Tips for Reducing Maintenance Costs.
The first crushing of the bauxite may often take place at the mine before transport to the alumina refinery if located nearby, or to the shipping port for export. At the refinery further crushing and/or washing may take place before the crushed bauxite is subjected to a grinding operation for final sizing before digestion. This chapter present ...
The process stages are: 1. Milling. The bauxite is washed and crushed, reducing the particle size and increasing the available surface area for the digestion stage. Lime and "spent liquor" (caustic soda returned from the precipitation stage) are added at the mills to make a pumpable slurry. 2.
The equilibrium solution pH and composition (24 h after bauxite addition) are reported in Table 12.4.India bauxite had a significantly higher equilibrium pH (pH 8.1 ± 0.1), compared to Guinea, Ghana, and USA bauxites (pH 6.6 ± 0.1, 6.5 ± 0.1, and 6.2 ± 0.4 respectively), which coincided with substantially higher concentrations of Ca and …
Bauxite Crushing Plant. Bauxite ore is a kind of mineral which is often collectively formed by gibbsite, a boehmite or a diasporeone. Bauxite can be widely used in many industries, among which the most important is to be used to refining aluminum, working as refractory and abrasive materials, and raw materials for high alumina cement.
