Abstract
A method for evaporating aluminium tri-halide comprises introducing finely divided solid tri-halide into a superheated gaseous stream thereof (e.g. at 600-800 DEG C.), preferably at a point intermediate the ends of the evaporating zone. The gas produced may be used in a sub-halide distillation process for the recovery of aluminium. In this process a portion of the AlX3 gas, from which the AlX has been removed by condensation, may be condensed to remove gaseous by-product impurities and a portion may be used as the gaseous feed to the evaporator of the invention. In Fig. 2 solid AlX3 67 is fed into the gas stream ascending from pipe 68 through plate 69 and the AlX3 vapour is drawn off through pipe 70. Specification 987,338 is referred to. <PICT:0987336/C6-C7/1>
