Embodiment 1
[0026] like figure 1 As shown, weigh 10kg of electrolytic manganese slag (derived from Sichuan Pingwu Manganese Industry), add 15 liters of tap water, place in the stirring reaction kettle and stir and wash for 1 hour, then filter with filter cloth, place the filtrate in a bucket, add Fumei 10 grams of sodium, 20 grams of wood activated carbon, stirred for 30 minutes, then stirred for 5 minutes after 2 hours, stood for 12 hours, filtered with filter cloth, added 400g of ammonium bicarbonate, stirred and reacted for 2 hours, and the reaction temperature was 20 ° C. After the reaction was completed, 500 L of carbon dioxide was introduced to dissolve and remove calcium and magnesium on the surface of manganese carbonate. After standing for 10 hours, vacuum filtration and washing were performed, and the solid was dried at 60° C. to obtain crude manganese carbonate. The filtrate was transferred to the self-made deamination equipment, 2Kg of quicklime was added, the agitator and the...
Embodiment 2
[0028] Weigh 10kg of electrolytic manganese slag (from Sichuan Pingwu Manganese Industry), add 15 liters of tap water, place in a stirring reactor, stir and wash for 1 hour, then filter with filter cloth, place the filtrate in a bucket, add 20 barium sulfide gram, 10 grams of wood activated carbon, stirred for 30 minutes, stirred for 5 minutes after 2 hours, stood for 12 hours, filtered with filter cloth, added 300g of ammonium bicarbonate, stirred and reacted for 2 hours, and the reaction temperature was 30 ° C. After the reaction was completed, add 100 L of carbon dioxide, after standing for 10 hours, vacuum filtration, washing 3 times, and drying the solid at 60°C to obtain crude manganese carbonate. The filtrate was transferred to the self-made deamination equipment, 1.5Kg of quicklime was added, the agitator and water pump were started, the negative pressure was removed, and the ammonia gas was collected by two-stage circulation under pressure with water, and carbon dioxid...
Embodiment 3
[0030] Weigh 10kg of electrolytic manganese slag (from Sichuan Pingwu Manganese Industry), add 15 liters of tap water, place in a stirring reaction kettle, stir and wash with water for 1 hour, then filter with a filter cloth, place the filtrate in a bucket, add 10% of sodium formate gram, 20 grams of wood activated carbon, stirred for 30 minutes, stirred for 5 minutes after 2 hours, stood for 12 hours, filtered with filter cloth, added 200g of ammonium bicarbonate, stirred and reacted for 2 hours, and the reaction temperature was 20 ° C. After the reaction was completed, add 100 L of carbon dioxide, after standing for 10 hours, vacuum filtration, washing, and drying of the solid at 60 ° C to obtain crude manganese carbonate. The filtrate is transferred into the self-made deamination equipment, 2Kg of quicklime is added, the agitator and the water pump are started, and the negative pressure is removed to remove ammonia. Carbon dioxide was introduced into the stage collection de...
