Other bauxite is treated after crushing by washing to remove some of the clay, reactive silica and sand waste; and then dried in rotary kilns. A substantial amount of aluminum is also recycled at such smelters. Subsequently, the majority of the resulting alumina produced from this refining process is in turn employed as the feedstock for the production of aluminum metal by the electrolytic reduction of alumina in a molten bath of natural or synthetic cryolite (Na3AlF6), the Hall-Hroult process.
