Bauxite Residue Management

Bauxite residue is mainly composed of iron oxides, titanium oxide, silicon oxide and un-dissolved alumina together with a wide range of other oxides which will vary according to the country of origin of the bauxite. The high concentration of iron compounds in the bauxite

EP0880468A1 - Bauxite treatment - Google Patents

Prior to the digestion of bauxite (which contains silica) in a digestion solution such as caustic soda for the production of aluminium oxide, the bauxite is mechanically activated to induce a mechanochemical reaction in the presence of a reagent such as lime. At least a portion of the silica is rendered insoluble and unreactive to the formation of sodium-aluminium-silicate desilication product

Bauxiet - Wikipedia

Bauxiet is genoemd naar het dorp Les Baux-de-Provence in het zuiden van Frankrijk, waar het in 1821 werd ontdekt door de Franse geoloog Pierre Berthier.In 1991 is de winning van bauxiet in Frankrijk gestaakt.. Bauxiet wordt verwerkt tot aluminium door het eerst om te zetten in het oxide (dit is het Bayerproces), en daaruit door elektrolyse van de smelt het metaal te maken.

Extraction of lithium and aluminium from bauxite mine

Sulphuric acid is a commonly used leaching agent in industry, such as in bauxite and spodumene leaching processes. However, for bauxite mine tailings, it is not effective to directly leach lithium and aluminium because tailings contain a large amount of clay minerals and have not undergone activation processes such as roasting.

ARTICLE: Addressing the Challenge of Bauxite Residue

Bauxite 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.


bauxite also include the minerals of iron, silicon, titanium, calcium and magnesium. A mixture may contain traces of minerals of a series of other ele-ments: N, K, P, Cr, V, Ga, Zn, Pb, Cu, Ni, Mn, C etc 1 . The Bayer process for alumina production in-volves the alkaline treatment of bauxite at high tem-

Secondary treatment - Wikipedia

Secondary treatment is a treatment process for wastewater to achieve a certain degree of effluent quality by using a sewage treatment plant with physical phase separation to remove settleable solids and a biological process to remove dissolved and suspended organic compounds. After this kind of treatment, the wastewater may be called as secondary-treated wastewater. Secondary treatment is the portion of

A cone crusher is similar in operation to a gyratory crusher, with less steepness in the crushing chamber and more of a parallel zone between crushing zones.bauxite secondary crushers for ore crushing,Bauxite ore in larger size will be fed into the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing.

Bauxite - an overview | ScienceDirect Topics

Bauxite. Bauxite is the most important ore of aluminum which contains only 3054% alumina, Al2O3; the rest is a mixture of silica, various iron oxides, and titanium dioxide along with trace amounts of zinc, phosphorous, nickel, vanadium etc., as indicated earlier.

Extraction of lithium and aluminium from bauxite mine

Bauxite mine tailings can be used as the reserve resources of aluminium and lithium. In this study, a less energy consumption treatment method for extracting aluminium and lithium from bauxite mine tailings has been proposed, which used mixed acid to leach aluminium and lithium from tailings directly, avoided roasting for reducing energy consumption, and obtained effective results.The minerals

The bauxite ore, Bayer process materials before precipitation, mud residue, and sand residue are therefore of radiological interest, whereas the alumina product is not. 8 Positional and personal monitoring data from bauxite mines and alumina refineries in Western Australia have been used to assess the above-background annual doses for the workforce across a range of jobs.

Red mud - Wikipedia

Red mud, also known as bauxite residue, is an industrial waste generated during the refinement of bauxite into alumina using the Bayer process.It is composed of various oxide compounds, including the iron oxides which give its red color. 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 also
