Most gallium is recovered as a byproduct of the extraction of alumina from bauxite, with recovery from the smelting of zinc ores as the second major source. Gallium’s nature as a byproduct, and the protective patents covering the recovery process prevent any precise measurement of reserves. Nonetheless the world’s bauxite reserves are estimated to contain over 100000 tonnes of gallium, and zinc resources 6500 tonnes. Only a small percentage is economically recoverable.
