Abstract
Chlorination processes of the oxides of main values contained in monazite, that is thorium, cerium, lanthanum and yttrium, were clarified by thermobalance method. The results indicated that the chlorination process is affected by the dehydration temperature of the hydrous oxide. On the chlorination of the oxides, the influence of a kind of carbonaceous materials was also examined; and the result showed that active carbon, sugarcoat were effective and graphite was not suitable.
