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).

    Bauxite Mine Tailings and Alumina Refinery Residue Storage

    Typically, both mine tailings and alumina refinery residue storage facilities are constructed of earthen embankments, or dikes, forming an enclosure. The mine and refinery by-products are deposited into the enclosure in a slurry form and dried over time.

    Reprocessing Gold Tailings by Gravity Methods

    A preliminary test has been carried out on a superpanner, on the tailings as such, and it has shown that the concentrates consist mainly of coarse particles containing mixed grains of gold and quartz, iron oxides and some tiny grains of gold and pyrite; however, very small grains of gold are entrained with the slimes into the residue.

    The residual crushed rock, or tailings, and water are then filtered and separated. The water is recycled back into the processing plant. At Twin Metals’ underground mine, the filtered tailings, by now the consistency of sand castle sand, will be transported to the dry stack area near the processing plant.

    A review of the risks posed by the failure of tailings dams

    Tailings dams are embankments constructed from waste rock to impound the tailings generated in a mine processing plant. Tailings are the by-product of extractive industries and are mixtures of crushed rock and processing fluids that remain after the extraction of economic materials from the mine resource (Kossoff et al, 2014).
