FIELD: chemistry.
SUBSTANCE: invention relates to chemistry and metallurgy and can be used to process alkaline aluminosilicate material through sintering. The method involves preparation of a mixture with an intensifying additive in form of fluorocarbon-containing aluminium production wastes in amount of 0.2-2.5 % of the weight of the dry mixture. The mixture is sintered at temperature 1150°-1260°C and the sintered mixture is leached.
EFFECT: invention lowers expenses, enables neutralisation and recycling of aluminium production wastes, increases output of alumina and alkali.
