Jamaica contains some of the largest known deposits of bauxite in the world. The mining areas are located in the western and central parts of the island. After mining, most of the bauxite is carried to alumina plants where it is refined into alumina. The alumina (or in some cases unrefined bauxite) is carried to export ports by rail.
Abstract. Bauxite is processed in alumina refineries by the Bayer process in which Al-containing minerals are dissolved in hot NaOH. The insoluble solids (bauxite processing residue mud and sand) are washed, sometimes partially neutralized (using CO 2 or seawater treatment), and deposited in impoundments surrounding the refinery using …

As a result, the country’s bauxite processing and crushing plants are essential contributors to the international aluminum supply chain. Economic and Social Impact:
Bauxite is a sedimentary rock mineral that is the primary source of aluminum. It is formed through the weathering of aluminum-rich rocks in tropical and subtropical regions. The name bauxite is derived from the French village of Les Baux, where it was first discovered in 1821 by geologist Pierre Berthier. Bauxite is typically found in layers …
This Chapter provides an introduction to the Bayer process and how the mineral composition of bauxites affects the process variants and the principal …
1. Introduction. Bauxite manufacturing by the Bayer process in alumina production is associated with a by-product, bauxite residue (BR), traditionally termed "red mud" (Xue et al., 2016, Xu et al., 2018).In turn, BR has raised environmental concern in areas affected by plant effluents as related to its recognized toxicity since early studies …
Our alumina processing offering is based on our proven, reliable proprietary equipment portfolio and our comprehensive service expertise. We provide complete solutions for alumina refineries from bauxite to alumina, as well as plant upgrades.
The Bayer process is the most commonly used refinement route, though certain countries use alternatives called the combined or parallel Bayer-Sinter process and the Nepheline-based process [20, 37].This section describes purely the Bayer Process. Due to the impurities in the bauxite ore, it requires treatment to produce purer alumina, Al 2 O 3 …

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 be ...

1. Introduction1.1.. ScopeThis document will critically review existing and potential processes for the processing of high silica bauxites. High silica bauxites are usually considered to be those with reactive silica contents in excess of ∼. 8% by weight of the bauxite (reactive silica is defined later in this paper).. This review is limited to …
The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.

This containment method prevents bauxite residue from inadvertently leaching into the groundwater. For this processing purpose, the company was the first in the country to establish a Bauxite Residue Processing Plant. With the new method implementation, this residue generation will be reduced further.
