Method of processing bauxites to produce alumina

A method for processing bauxites to produce alumina, said method comprising:

• filtering an alumina slurry obtained after a digestion of the bauxites, wherein the alumina 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, wherein:
• the washing is carried out with hot water, at a temperature of below 98° C. to achieve specified concentrations of the green liquor and a liquid phase of the red mud,
• the filtrate is subjected to security filtration or precipitation,
• 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, and
• a resulting cake is a waste product.
