TENORM: Bauxite and Alumina Production Wastes

Waste Generation, Disposal and Reuse Wastes can be generated at several points in the production process, including during the mining of the bauxite ore, and during the refinery production process. The refinery processes used to produce aluminum generates about 2 2.5 tons of solid waste for every 1 ton of aluminum produced.

Management and use of bauxite residue

Another disposal technique adopted by some plants was sea or river disposal particularly in the 1940s to 1960s. In at least six plants, two located in France (Gardanne and La Barasse), one in Greece (Distomon) and three in Japan (Shimizu, Ehime, Yokohama), bauxite residue was discharged into the sea either via pipelines or from ocean going vessels.

Bauxite tailings Wikipedia

Bauxite tailings, also known as bauxite residue, red mud, red sludge, or alumina refinery residues (ARR), is a highly alkaline waste product composed mainly of iron oxide that is generated in the industrial production of alumina (aluminium oxide, the principal raw material used in the manufacture of aluminium metal and also widely used in the manufacture of ceramics, abrasives and refractories).

Mining and Refining Jamaica World Aluminium

At one of the disposal sites in Jamaica, the bauxite residue had been deposited in depressions left after bauxite mining. When deposited, the residue had a solids content of approximately 20% but it was discharged in a way that in most cases, when full and aged, no residual pond water remained resulting in a relatively dry surface with a pH of about 11.
