after the bauxite is crushed, it is wet milled with lime and recycled mother liquor to make a qualified pulp. The slurry is pre-desiliconized and preheated to the dissolution temperature for dissolution. After the dissolved pulp is cooled by auto-evaporation, it enters into the sedimentation and separation process of diluting and red mud (solid residue after dissolution). The secondary steam generated from the evaporation process is used for preheating of the pulp. After sedimentation and separation, the red mud is washed into the red mud storage yard, and the separated crude liquid (sodium aluminate solution containing solid float, the same below) is sent to the leaf filter. The crude liquid is called semen after removing most of the suspended matter by leaf filtration. The semen enters the decomposition process and is decomposed by seed to give aluminum hydroxide. After the decomposed aluminum hydroxide is fractionated and separated and washed, part of it is returned to the seed decomposing process as a seed crystal, and the other part is calcined to obtain an alumina product. The decomposed mother liquor separated after the seed crystal is decomposed is evaporated to return to the dissolution process and a closed loop is formed. Aluminum hydroxide is calcined to give alumina.
