Mineral Resource of the Month: Gallium
Ultra-pure gallium has a brilliant silvery appearance, and the solid metal exhibits conchoidal fracture similar to glass. Most gallium is produced as a byproduct of treating bauxite (aluminum ore), and the remainder is produced from zinc-processing residues. So its production is dependent on the production of those principal metals.
