Bauxites are typically classified according to their intended commercial application: abrasive, cement, chemical, metallurgical, refractory, etc. The bulk of world bauxite production (approximately 85%) is used as feed for the manufacture of alumina via a wet chemical caustic leach method commonly known as the Bayer process.

RASC Bauxite RASC (refractory Aggregate Super Calcined) bauxite is rotary calcined. The bauxite raw material is extremely consistent which LKAB Minerals process into different gradings for use in the refractory industry or as an aggregate in High Friction Surfacing. Other bauxites LKAB Minerals can source Chinese Bauxite materials upon request.

Bauxite Bauxite, the raw material for the production of alumina, was first discovered in 1924 at Kijang, Bintan Island, in the province of Riau, in northwestern Indonesia. Bauxite from Bintan Island has been mined and exported since 1935. In 1968 ANTAM acquired the mine. Thus, ANTAM is Indonesia's longest running producer of bauxite.

At present, BMGG produces 1.5m. tpa metallurgical grade bauxite, 300,000 tpa RASC calcined bauxite, 200,000 tpa chemical grade bauxite, and 200,000 tpa cement grade bauxite. Bosai's bauxite mine at East Montgomery, Linden, Guyana; a US$23m expansion plan has been announced for a new kiln for refractory grade bauxite.

There are many different standards used in grading, however, the three you are most likely to encounter are: ACS, Reagent Grade and Laboratory Grade. Varying terminology is often used by different chemical manufacturers but as a general rule of thumb, ACS and Reagent Grades are usually the purest with Laboratory Grade being less pure.

Bauxite is an aluminium-rich ore used for the manufacture of aluminium (metallurgical bauxite) and refractory products, chemicals or cements. Bauxite is a prime important raw material for the primary aluminium industry. It is also used in a number of non-metallurgical sectors, like refractory, abrasive, cement, steel making and chemicals.

Bauxite does not have a specific composition. It is a mixture of hydrous aluminum oxides, aluminum hydroxides, clay minerals, and insoluble materials such as quartz, hematite, magnetite, siderite, and goethite. The aluminum minerals in bauxite can include: gibbsite Al (OH)3, boehmite AlO (OH), and, diaspore, AlO (OH). Physical Properties

Bauxite is the principal aluminium ore. It is formed as a residual product over millions of years by chemical weathering of rocks containing aluminium silicates. It was first discovered in France in 1821, and has since been found in many locations around the world. Hydro has interests in two bauxite mines in Brazil. Key features

Bauxite is the major alumina (Al 2 O 3 ) bearing ore used in the aluminum manufacturing industries. The bauxite containing less than 50% Al 2 O 3 is called low-grade bauxite ore which is commonly used for the alumina …

There are four basic grades of bauxite- Chemical grade- (55-58% min. pure), Abrasive grade- (55% min. pure), Refractory grade- (59-61% min. pure) and Metallurgical grade- (50-55% …

BAKER —A grade of chemicals for laboratory use, for organic synthesis, and for routine research usually controlled by physical criteria and often by assay (by GC). Practical —Chemicals of sufficiently high quality for use in diverse applications. Some products may contain intermediates, isomers, or homologs.

Chemical Grade Alumina (CGA) is a versatile product used in detergents, flame retardants, adhesives, paints, and more. Chemical grade alumina comes in two forms: wet cake and dry hydrate. Wet Cake (WH-30) is a high purity alumina trihydrate produced by the Bayer Process. It has the consistency of damp beach sand.

The most widely used chemical process of refining bauxite into alumina, the Bayer process, involves dissolving the Al2O3 out of the bauxite rock with caustic soda (NaOH) at elevated temperature and pressure. The Al2O3 fraction of the bauxite is dissolved into solution, to later be precipitated out as alumina.

The chemical composition of the refractory grade bauxites is presented in Table III. The prime difference between the Brazilian refractory grade bauxite and the Chinese one was the amount of iron and titanium oxides, in which Brazilian sample was richer in iron (3.80%) and the Chinese sample was richer in titanium (3.59%).

Bauxite occurs in the low lying plateaus of 100 m to 300 m above mean sea level and formed by the laterisation of the aluminium bearing sediments (siltstone) and dolerites. Bauxite is characterized by fairly low silica content (about 2.5% SiO 2 - only half is reactive) and medium to high alumina (46-48%).
