Alumina is the primary raw material used in the production of aluminum. Balco currently sources in excess of 60% of its alumina from third party suppliers on both the indian and international markets, with the remainder provided by its alumina refinery. The alumina sourced externally is metallurgical grade calcined alumina with a minimum alumina content of 98.60% on a dry basis.
Power is a key input at balco’s korba facility, where it is provided by two coal-based captive power plants of 270 mw and 540 mw, respectively. On-site diesel generators provide power for balco’s mines.
Balco's business has a number of elements which are summarized in the following diagram:

Balco produces primary aluminum in the form of ingots and wire rods for sale. Ingots are used extensively for aluminum castings and fabrication in the construction and transportation industries. Wire rods are used in various electrical applications especially in the form of electrical conductors and cables.
Rolled products, namely coils and sheets, are value-added products that balco produces from primary aluminum. Rolled products are used for a variety of purposes in different industries, including aluminum foil manufacturing, printing, transportation, consumer durables, building and architecture, electrical and communications, packaging and general engineering industries.
Vanadium sludge is a by-product of the alumina refining process and primarily used in the manufacture of vanadium-based ferro alloys.
