FIELD: technological processes; mining.
SUBSTANCE: invention relates to a method of processing alumina-containing material and can be used in sintering technology of producing alumina and soda products from nepheline ore. To reduce consumption of nepheline ore in a nepheline-limestone-soda charge, ash-slag wastes are added in an amount from 0.1 to 10 % of weight of nepheline ore.
EFFECT: nepheline ores and recycling of ash-slag wastes with post-extraction of valuable components therefrom.
