Examples
example 1
[0043] The moisture content of by-product red mud (moisture content 40% by weight (weight), solid basis 6.0kg) and activated carbon powder (below 200 orders, 4.0kg) is adjusted to 35% by weight and then put into a kneading mixer, After mixing at 80 rpm for 30 minutes, shape was formed with 5mm die extruder.
[0044] Put the extruded shaped body into a drier, dry it at 105°C for 2 hours, and after calcining it at 950°C for 2 hours, put the calcined object (9.5kg) into 5% by weight hydrochloric acid solution (45 liters ) for 2 hours, the temperature was 60°C, then the shaped body and the solution were separated, and the shaped body was washed with 100 liters of water, followed by injecting 10% by weight ferric chloride solution for 4 hours with a solid basis of 1:1 under the condition of maintaining 40°C. The solid and the solution were separated, washed with drained water, and finally dried in a fluidized bed dryer at 90°C for 4 hours to obtain 18.5 kg of shaped bodies.
example 2
[0046] The moisture content of by-product red mud (moisture content 40% by weight (weight), solid basis 6.2kg) and activated carbon powder (below 200 orders, 4.3kg) is adjusted to 35% by weight and then put into a kneading mixer, After mixing at 80 rpm for 30 minutes, shape was formed with 5mm die extruder.
[0047] Put the extruded molded body into a drier, dry it at 105°C for 2 hours, and calcinate it at 950°C for 2 hours, then put the calcined object (9.9kg) into 5% by weight sulfuric acid solution (45 liters ) for 2 hours, the temperature was 60°C, and then the shaped body and the solution were separated, and the shaped body was washed with 100 liters of water, and then kept at 40°C with a 1:1 solid basis to inject 10% by weight copper sulfate solution for 4 hours. The solid and the solution were separated, washed with drained water, and finally dried in a fluidized bed dryer at 90°C for 4 hours to obtain 18.8 kg of shaped body.
example 3
[0049] The moisture content of by-product red mud (moisture content 40% by weight (weight), solid basis 6.0kg) and activated carbon powder (below 200 orders, 4.0kg) is adjusted to 35% by weight and then put into a kneading mixer, After mixing at 80 rpm for 30 minutes, shape was formed with 5mm die extruder.
[0050] After putting the extruded molded body into the drier, dry it at 105°C for 2 hours, and then calcined it at 950°C for 2 hours. liter) for 2 hours, the temperature was 60°C, then the shaped body and the solution were separated, the shaped body was washed with 100 liters of water, and then maintained at 40°C with a 1:1 solid basis to inject a 10% by weight lead sulfate solution for 4 hours. The solid and the solution were separated, washed with drained water, and finally dried in a fluidized bed dryer at 90°C for 4 hours to obtain 18.4 kg of shaped body.
