Process: Process for beneficiation of low grade bauxite ore (with ferruginous/silicious impurities) for metallurgical refractory use.

Uses: Bauxite for production of aluminium, abrasives, refractories, cement and chemicals.

Salient Technical Features: Simple process for lowering of silica and iron and enrichment of alumina.

Environmental Considerations: No deletarious effects on environment from process rejects.

Scale of Development: 25 tpd scale.

Commercialisation Status: Ready for commercialisation.

Major Raw Materials: Bauxite ore, flotation reagents (if required).

Major Plant/Equipment/Machinery: Crusher, Scrubber, Grinder, Magnetic separator, Flotation unit, Filter, Thickener (a combination of one or more units depending upon the nature of the raw material).

Techno-Economics: To treat 1 ton/hr, a capital cost of 180-240 lakhs depending upon the unit operations required.

Technology Package: Raw material evaluations, process know-how, technological flow sheet with material balance, equipment details. Assistance in setting up and commissioning of the plant on separate terms.
