By double decomposition of water in the reactor or steam dissolved manganese sulfate, filtered insoluble objects, and then purified hydrogen sulfide to remove heavy metals and other impurities, heated to boiling, filter it when it was hot, prepared pure manganese sulfate solution. Then in the reactor with ammonium bicarbonate solution at 25 ~ 30 ℃ under the metathesis reaction of manganese carbonate, precipitated via suction filtration, washing, dehydration after 80 ~ 90 ℃ under air drying, manganese carbonate product obtained .

The nature and use of manganese carbonate
Chemical properties: pink triangle crystal diamond crystal or amorphous white brown powder. It is almost insoluble in water, slightly soluble in water containing carbon dioxide. It is soluble in dilute inorganic acid, slightly soluble in common organic acid, insoluble in alcohol and ammonia. Its wide range of uses: as a catalyst for desulfurization, enamel paint, manganese salt, raw materials can also be used for fertilizer, medicine, feed additives, welding supplies and other purposes.
