Experimental study of the anaerobic digestion of palm oil mill effluent (POME) was carried out in an anaerobic upflow sludge blanket reactor (UASBR) with bauxite residue. The production rate of methane 114 L/gCOD/d and CH 4 concentration was 205 L gCOD/d at 8.5 g/L of bauxite residue in UASBR.
Bauxite. Bauxite ore is the primary raw material that is refined into alumina and later sent to our smelters where it is processed into aluminum. Consistent. Reliable. Sustainable. Our leading position in mining is built on our ability to meet customer-specific needs for high-quality, sustainably produced material.
For recent statistics, please go the the Bauxite and Alumina Statistics and Information page. Bauxite is a naturally occurring, heterogeneous material primarily composed of one or more aluminum hydroxide minerals and various mixtures of aluminum silicate (clay, etc.), iron oxide, silica, titania, and other impurities in minor or trace amounts.
In 2015, the US Geological Survey estimated that over 95% of bauxite was converted to alumina, with the remainder going toward a variety of products such as abrasives, chemicals, proppants, and more. The primary approach to transforming bauxite ore to alumina is …

Bauxite is the principal ore of aluminum and is a mixture of aluminum oxides and hydroxides that formed from intense chemical weathering of a soil in tropical environments. Soils formed under these conditions are termed laterites. In Arkansas, the aluminum-enriched soils are the result of the decomposition and lateritic weathering of nepheline syenite, an intrusive …

Bauxite ore is crushed in a high temperature, rotating grinding mill, where it is mixed with sodium hydroxide. This produces a slurry (thick liquid) of sodium aluminate and small amounts of other metals. 2. SLURRY TANK: The 'other metals' are heavier than the sodium aluminate and sink to the bottom of the slurry tank, where they are removed. 3.
