Abstract: The invention provides a process for recovering aluminum values from aluminum-containing minerals, such as oxides of aluminum and aluminosilicates.The process involves heating an intimate mixture of an aluminum-containing mineral and a solid carbonizable organic material, preferably a fibrous cellulosic material, so as to carbonize the organic material, and chlorinating the solid residue from the carbonization step. The solid residue contains carbon in very finely divided form distributed throughout the aluminum-containing mineral. The surface area and reactivity of this carbon is much higher than that of powdered coal and the chlorination reaction thus takes place in a most efficient manner.

Such complex solids have a high degree of solubility in anhydrous alcohol and a high compatibility with halogenated hydrocarbons, thus making the complexes suitable for aerosol formulations and particularly antiperspirant compositions.

Abstract: An aqueous solution containing fluorides, for example, hydrofluoric acid, is reacted with commercial grade aluminum oxide comprising predominantly alpha alumina at an elevated temperature to produce a complex aluminum hydroxide fluoride hydrate that precipitates from the solution. The commercial grade aluminum oxide contains an amount of gamma and delta alumina such that the aluminum oxide has a loss of weight on ignition of from about 0.5% to about 2.5%. The resulting aluminum hydroxide fluoride hydrate precipitate is recovered and calcined in a non-oxidizing atmosphere to produce aluminum fluoride suitable for use in the electrolytic production of aluminum.
