FIELD: chemistry.
SUBSTANCE: preparation ofraw materials is carried out by treating it sequentially or in parallel with division into batches and their subsequent mixing after treatment with three types of active concentrated solutions: sulfuric acid-ozonide-peroxide, nitric acid-peroxide, and peroxide-carbonate, produced by photochemical and electrochemical treatment of the initial aqueous solutions, respectively, sulfuric acid and/or sulfuric acid-peroxide, nitric acid, alkali metal carbonates, followed by the pelletization with these solutions or after doped impregnation of the non-pelletized mineral mass after the formation of the stack.
EFFECT: increasing the effectiveness of the method for processing refractory carbonaceous ores and technogenic mineral raw materials due to more complete oxidation of carbonaceous material and opening the mineral matrixes of sulphide minerals.
