FIELD: chemistry, inorganic.
SUBSTANCE: invention is related to the field of chemical and hydrometallurgical technology and can be used for decomposition of silicate ores and utilisation of slags of metallurgical and coal industries. The method of separation of mineral oxide mixture into individual components includes the steps of hydrofluorination at a temperature of 150 - 200 °C by means of ammonium fluoride, sublimation separation of volatile fluorides at 350 - 400 °C, pyrohydrolysis, leaching of soluble fluorides from the fluorinated mass, ammonia precipitation of insoluble hydroxides, filtering separation, hydrochlorination at a temperature of 200 - 250 °C by means of ammonium chloride. The proposed invention allows separation of mineral raw stock into individual components, reuse of reagents being possible.
EFFECT: separation of mineral raw stock into individual components with a possibility of reuse of reagents.
