The results of studies of the chemical and mineralogical characteristics of alumina-containing wastes of the gas processing industry and the possibilities of their use for the synthesis of aluminum-magnesium spinel are presented. It was found that the optimal condition for the synthesis of spinel MgAl 2 O 4 by the sol-gel method using alumina-containing waste is a temperature of 1000 ° C and a holding time of 120 min.
