Zusammenfassung:FIELD: processing nepheline ores for forming source of raw materials for alumina industry. ^ SUBSTANCE: proposed method includes preparation of nepheline-soda-lime charge from low-quality nepheline ores at content of Al2O3 lesser than 25% and addition of high-quality nepheline ore at content of Al2O3 no less than 26.5% to ensure content of Al2O3 in nepheline ore mixture of 23.9-25.9%. Bauxite is additionally added to charge in the amount of 10-20% of weight of mix at content of Al2O3 of 40-53%. Then, sintering and hydrochemical treatment are performed for obtaining alumina and soda products. ^ EFFECT: enhanced efficiency of processing low-quality nepheline ores. ^ 5 tbl, 8 app, 4 ex
