METHOD OF PROCESSING NEPHELINE ORE Russian patent published in 2017 - IPC C22B21/00 C01F7/38 C22B1/14 C22B3/04

Abstract RU 2606821 C1

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.
