| description | Disclosed is a method for processing bauxites to produce alumina comprising: filtering an alumina slurry obtained after a digestion of the bauxites, the slurry, after leaching, dilution or thickening, is filtered at a temperature of at least 95° C. to obtain a filtrate representing a green liquor after the filtration and a solid phase of a red mud on filtration equipment; and washing the solid phase of the red mud on the filtration equipment, the washing being carried out with hot water at a temperature of below 98° C. the filtrate being subjected to security filtration or precipitation, and the water after washing the red mud on the filtration equipment is fed for dilution of the alumina slurry after the digestion of the bauxites or dilution of the filtrate to obtain a specified concentration of the green liquor, wherein a resulting cake is a waste product. |
