Abstract
Results are presented of a study aimed to recover lanthanum in the presence of aluminum from acid solutions obtained in leaching of a spent cracking catalyst by precipitation with a solution of ammonia and sodium hydrocarbonate. The conditions for selective precipitation of lanthanum were examined. The composition and properties of the resulting lanthanum-containing precipitates were analyzed. Various variants of their use are suggested.
