A separation method of red mud in alumina production process relates to a liquid-solid separation method of digestion red mud slurry in the process of the alumina production. The invention is characterized in that the red mud slurry of the alumina production is filtered and separated by directly adopting a microporous filter to obtain filtrate and dehydrated red mud. The type of a filter press used for filtrating and separating is a SK-PGK type, and the technical process is that: material feeding, filtration, washing, dry pressing, residue discharging, regeneration, material feeding and so on; the parameters of the technique are that the pressure is 0.20-0.70 MPa, the temperature is 60-150 DEG C, the flux is 10 m3/h, the filtrating area is 5-200 m3, solid in the digestion red mud is 50-180 g/L, suspended material in the filtrate is not more than 0.005 g/L, filtrated cake containing water is not more than 20 percent. The method of the invention simplifies the technical process, uses no flocculant ...
