Abstract
A process for the recovery of aluminum from aluminum-containing alloys, by paying a stream of gaseous aluminum trihalide upwards through an alloy nasa moving downward, in granular form, in a zone of conversion to the which is maintained at the reaction temperature in excess of 1000º C to generate aluminum monohalide, which is cooled in a condensation zone to effect the deposition of metallic aluminum, the solid alloy having a negative thermal coefficient of resistivity over a range of temperatures below said reaction temperature, characterized in that said solid alloy is preheated in granulated form before its introduction into the conversion zone by continuously advancing the solid alloy through a preheating zone and simultaneously passing a current of heating through said alloy in an even direction it alleviates its movement to raise the temperature of said alloy to a temperature at least above the lower limit of the range of negative thermal coefficient of resistivity, while the advance of the solid alloy includes communicating pulses to the granulated alloy mass in a manner of producing the relative displacement of the points of contact between adjacent particles, said pulses being applied with sufficient frequency to prevent a substantial surface melting of the particles at the contact points between particles.
