Mining and Refining – Australia

Oxalate forms in the alumina refining process as a result of organic material in bauxite ore. Organics enter the refinery liquor stream when bauxite is digested in caustic soda. This organic matter is broken down as part of the Bayer process with sodium oxalate being the predominant end product. This is an impurity that must be removed for optimum alumina production and quality. To prevent an eventual

Bauxite Mining and Alumina Refining: Process

Solar ultraviolet exposures in surface bauxite mining operations and alumina refineries are likely to contribute to the occurrence of squamous cell and basal cell carcinomas, although this is an inference drawn from studies of outdoor workers in other industries. 9–11 Control measures include the use of enclosed mobile equipment cabins, the scheduling of outdoor on-foot work to avoid near midday

Mining and Refining – Ireland

The Bayer process is an energy-intensive technology and consumes large amounts of fuel oil and energy. To satisfy the refinery’s demand for energy, a 160 megawatt Combined Heat Power Plant (CHP Plant) was built on the site of Rusal Aughinish. Currently, the CHP Plant generates steam and power for the refinery and supplies surplus power to the national power grid. All fuel requirements use natural gas at

Bauxite in Jamaica - Geo for CXC

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. Most of Jamaica’s bauxite is refined into alumina and the rest is exported unrefined. The marketing of bauxite

Red mud - Wikipedia

Red mud, formally termed bauxite residue, is an industrial waste generated during the processing of bauxite into alumina using the Bayer process.It is composed of various oxide compounds, including the iron oxides which give its red colour. Over 95% of the alumina produced globally is through the Bayer process; for every tonne of alumina produced, approximately 1 to 1.5 tonnes of red mud are ...
