Abstract
Process for obtaining alumina from materials containing alumina or silicic acid, these materials being treated in the furnace with additions of CaO and the alumina is then extracted from the furnace calcining product, characterized in that it is added to the materials Raw materials, if they do not yet contain it, iron oxide, for example Fe2O3, a molten slag is produced and the furnace is operated so reductively and at such low temperatures that ferrous oxide silicate (2FeO.SiO2) is formed.
