Abstract
Bayer liquor is the principal source for gallium production. India is a large aluminium producing country and thus has a vast potential to produce gallium to the tune of 10 to 12 TPA from its five alumina plants. Various options are available for obtaining gallium metal from Bayer liquor depending on the history and quality of the liquors which vary from plant to plant through one of the following technologies viz., amalgam metallurgy, cementation of gallium with aluminium or aluminium-gallium alloys, solvent extraction and ion exchange resins. The merits and otherwise of the various technologies will be discussed with reference to their feasibility of commercial scale adoption in Indian Alumina plants, and their impact on the economy of alumina production. The world scenario of gallium production and consumption will also be dealt with
