Abstract:
     The invented method includes the following steps: when the aluminium oxide is produced by using high-iron trihydrate alumyle as raw material, feeding the slurry dissolved out from dissolution procedure and red mud washing liquor from settling procedure into dilution trap together, then feeding the diluted slurry into the hydroclone group to make coarse and fine red mud grading operation, making bottom flow of the hydroclone be fed into coarse red mud slurry channel and settling procedure coarse red mud treatment system and making overflow of the hydroclone be fed into fine red mud slurry channel and settling procedure fine red mud treatment system.
