Charles S Hutchison, in Geology of North-West Borneo, 2005. VIII.5.2 Bukit Gebong. Bauxite has been formed from gabbro on the steep-sided Bukit Gebong (334 m). The deposit was estimated to contain a mineable 1.5 Mt of washed bauxite with an average composition of 49.4% alumina (Wolfenden and Haile, 1963).The bauxite formed a bed averaging 2 m thick

    Mar 11, 2019 · The carbonation plant found that the neutralization of bauxite residue was dependent on the concentration of CO 2, total flow rate of gas, and agitation speeds. The amount of CO 2 sequestered by red mud liquor was 1.4 g/kg red mud. Alcoa’s process at present requires only 30-35 kg CO 2 per tonne of red mud (dry weight)

    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 igneous rock. During the
