FOCUS: Pricing bauxite and alumina

Bauxite plays catch-up Unlike the alumina market, the bauxite industry is yet to reach a consensus on pricing mechanisms, beyond long-term, fixed-price contracts. Further upstream in the aluminium supply chain, spot market volumes are thin and still reflect a minority of the sales book that is not captured by integrated activities or long-term contracts.

Relationships between alumina and bauxite dust exposure

2020/8/25Bauxite ore is surface-mined for its aluminium oxide content and refined to alumina (a white granular powder), which is then used in aluminium production. No consistent associations with respiratory symptoms or lung function have been observed with either dust,1 2 although high exposure to alumina may be possibly associated with scanty, small irregular opacities in the lungs.3 Both bauxite Get price

A new heterotrophic strain, named Providencia sp. JAT-1, was isolated and used in bioleaching of low-grade complex copper ore. The strain uses sodium citrate as a carbon source and urea as a nitrogen source to produce ammonia.

mining bauxite ore

View a high magnification image of a bauxite ore thin section. The Bayer process, still economically the most feasible method for extracting aluminum from bauxite ore, involves mining, dissolving the alumina at an elevated temperature, adding flocculants, precipitating pure gibbsite, and heating the gibbsite to 1,100 degrees Celsius to yield alumina by calcination.

ARTICLE: Addressing the Challenge of Bauxite Residue

2019/3/11Bauxite ore contains 30-60% aluminum oxide (Al 2 O 3). In the Bayer process (Figure 2), the bauxite is digested in a pressure vessel along with a sodium hydroxide solution (caustic soda) at an elevated temperature, which dissolves the aluminum oxide converting it into sodium aluminate, leaving insoluble red mud solids as a by-product.
