FIELD: machine building.
SUBSTANCE: invention relates to the bauxites processing system with the alumina production therefrom. System contains sequentially located bauxite in the cycling solution grinding mill, dryer, first agitator for leaching, thickener, washer, second agitator for desiliconization, decomposer, tube furnace, at that, after the washer the sludge in the diluted sulfurous solution leaching third mixer, connected to the third mixer by the feeding pulp pipeline filtering device, as well as a briquetting press for the high-iron red sludge compaction, connected to the filtering device by the conveyor, and connected to a filtering device by the discharge pipe extractor for the REM salts extraction are installed.
EFFECT: enabling increase in the alumina-containing raw materials processing complexity.
