Example Embodiment
[0015] Example 1
[0016] The diluted slurry has a solid content of 10g / l, caustic Na 2 O K The concentration is 140g / l, the diluted slurry is pumped into the cyclone group, the solid content of the underflow is 90g / l, and the solid content of the overflow is 5g / l. The underflow of the cyclone enters the rubber belt filter for filtration and washing, the filtrate is mixed with the overflow of the cyclone, and the red mud filter cake is removed to the red mud storage yard; the overflow of the cyclone is pumped into the high-efficiency solid-liquid separator, and the filtrate is solid The content is less than 30-15mg / l, it is the decomposing process of sodium aluminate refined liquid; the filter cake is washed in the washing settling tank, and after washing, it is discharged to the red mud storage yard.
Example Embodiment
[0017] Example 2
[0018] After dilution, the solid content of the slurry is about 250g / l, caustic Na 2 O K The concentration is 250g / l, the diluted slurry is pumped into the cyclone group, the solid content of the underflow is 400g / l, and the solid content of the overflow is 50~200g / l. The underflow of the cyclone enters the rubber belt filter for filtration and washing, the filtrate is mixed with the overflow of the cyclone, and the red mud filter cake is removed to the red mud storage yard; the overflow of the cyclone is pumped into the high-efficiency solid-liquid separator, and the filtrate is solid The content is less than 30mg / l, which is the decomposing process of sodium aluminate refined liquid; the filter cake is washed in the washing settling tank, and after washing, it is discharged to the red mud storage yard.
Example Embodiment
[0019] Example 3
[0020] After dilution, the solid content of the slurry is about 80g / l, caustic Na 2 O K The concentration is 200g / l. The diluted slurry is pumped into the cyclone group, the solid content of the underflow is 200g / l, and the solid content of the overflow is 100g / l. The underflow of the cyclone enters the rubber belt filter for filtration and washing, the filtrate is mixed with the overflow of the cyclone, and the red mud filter cake is removed to the red mud storage yard; the overflow of the cyclone is pumped into the high-efficiency solid-liquid separator, and the filtrate is solid The content is less than 30mg / l, which is the decomposing process of sodium aluminate refined liquid; the filter cake is washed in the washing settling tank, and after washing, it is discharged to the red mud storage yard.
