ABSTRACT
A modern approach to metallurgical production requires the implementation of technological solutions to reduce the amount of waste generated. The possibility of processing nepheline sludge into a calcareous component by means of combined conversion is proposed. The product of sludge disposal in this case is calcium carbonate, silica gel and soda solution. The developed methods for processing nepheline sludge are simple, low cost of implementation and can be carried out on typical equipment for alumina production, that will allow to diversify production. The described approach allows to increase the economic efficiency of production.
