Bauxite ore resources in India

India is a major mineral producer in Asia and globally. It is currently a global producer of chromite, coal, iron ore and bauxite. Bauxite is an ore of Aluminium and is a term for sediments rich in alumina but low in alkalis, alkaline earth and silica. The term is also extended to cover lateritic weathering products rich in gibbsite on basalt. The production of aluminium consumes over 90% of world production of bauxite, while the reminder is used for abrasives, chemicals and refractory. The term bauxite ore is applicable to bauxites, which are economically mineable containing not less than 45-50% Al2O3 and not more than 20% Fe2O3, and 3-5% combined silica. The term alumina refers to pure Al2O3 containing 52.9% Al and 47.1% O.

Bauxite deposits originate from weathering or soil formation with enrichment of aluminum. The parent rock of bauxite may be (1) igneous and metamorphic rocks, (2) sedimentary rocks. Bauxite deposits on igneous and metamorphic rock are known to have formed throughout the Earth’s history on plateaus. Examples of slope type deposits are on : basic to intermediate volcanic rocks, acid metamorphic rocks and charnockites in south India. Conditions which favour and the formation of bauxites are permeability, high temperature climate with continuous rainfall, location of source rock in topographically high and well drained areas, availability of pure rain water than the organic acids which will decrease the quartz dissolution, pH between 4-10, dense vegetation, bacteriological action, a mature topography permitting accumulation of the weathered products and free movement of the water table with minimum erosion.

Bauxite ore beneficiation methods

Beneficiation of ores may be defined as the method of upgrading and enriching the useful mineral content of the ores, by removing undesirable and deleterious components. The processes adopted depend on the physical and chemical characteristics of the ore minerals, to take advantage of properties like specific gravity, magnetism, surface characteristics etc. The beneficiation processes normally employed are washing ; gravity concentration - jigging, heavy media separation, spiraling and tabling ; and magnetic separation and flotation. Most of the bauxite ores are being presently subjected to beneficiation ranging from simple crushing, classification, washing and jigging to heavy media separation, also known as sink-float separation, to achieve higher recovery of saleable ore and to obtain a high grade concentrate.
