Severe traumatic injuries and fatalities are rare in bauxite mining and alumina refining, but if they do occur, there is the potential for posttraumatic stress disorders to develop in witnesses, colleagues, and managers. ACKNOWLEDGMENT. The authors thank Mr Russell Williams, previously Vice President—Mining Projects—Alcoa World Alumina, for providing information detailed in the process

Bauxite mining and alumina refining: process description

To describe bauxite mining and alumina refining processes and to outline the relevant physical, chemical, biological, ergonomic, and psychosocial health risks. Methods Review article. Results The most important risks relate to noise, ergonomics, trauma, and caustic soda splashes of the skin/eyes. Other risks of note relate to fatigue, heat, and solar ultraviolet and for some operations

Participation in Bauxite Mining and Alumina Refining

The Worsley Alumina JV is an integrated project that consists of two operations in the south west of Western Australia a bauxite mine near Boddington and an alumina refinery near Collie ("Worsley Alumina Project"). The project has a production capacity of 4.6 million tons of alumina per year.

Mining and Refining Process World Aluminium

Mining and Refining Process Aluminium is the most abundant metal in the earth’s crust. The aluminium-containing bauxite ores gibbsite, böhmite and diaspore are the basic raw material for primary aluminium production. Proven, economically viable reserves of bauxite are sufficient to supply at least another 100 years at current demand.

Rusal Aughinish Alumina is the largest alumina refinery in Europe and the largest of the alumina facilities operated by UC RUSAL. The plant was built between 1978 and 1983 and had an initial rated capacity of 800,000 tonnes a year. The current annual capacity of the refinery is in excess of 1.9 million tonnes of alumina.

Bauxite and Alumina: Growth Maintained E & MJ

The development of alumina-refining capacity has run hand-in-hand with rising bauxite production, although not necessarily in the same localities. Existing infrastructure has been a key factor in this respect with, for example, Jamaica’s bauxite initially being refined in the USA and elsewhere until domestic capacity came on stream. Guinean bauxite production is in the same position today

Mining and Refining Process World Aluminium

Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina refineries tend to be located close to bauxite mines and/or ports for efficient

Bauxite mining and alumina refining: process description

Exposures to bauxite dust, alumina dust, and caustic mist in contemporary best-practice bauxite mining and alumina refining operations have not been demonstrated to be associated with clinically significant decrements in lung function.

Mining and Refining Energy Efficiency

Bauxite mining requires relatively low energy inputs, compared to other steps in the aluminium production process with less than 1.5 kilograms of fuel oil (mainly in the form of diesel for haul trucks) and less than 5 kWh of electricity consumed per tonne of bauxite extracted.

Alumina Limited

Bauxite is generally washed, ground and dissolved in caustic soda (sodium hydroxide) at high pressure and temperature at an alumina refinery. Approximately four tonnes of bauxite produces one tonne of alumina and approximately two tonnes of alumina are required to produce one tonne of aluminium.

BRAVO Bauxite Residue and Aluminium Valorisation

In 2011, European countries produced 3.2 million tonnes of bauxite out of the 15.5 million tonnes bauxite needed for their alumina production (6.8 million tonnes alumina). A further import of 4.0 million tonnes of alumina was needed to fulfil the demand of the primary aluminium producers in Europe.
