manganese carbonate powder,
Liangjiang brand- manganese carbonate, adopting direct acidification method for soft manganese ore powders (two-ores method), oft manganese ore is Calcined into manganese oxide and then acidification, reduced the calcination process, greatly saves equipment investment, reduce the pollution of the environment, and reduce the cost.The appearance is rosy, triangular crystal or amorphous bright white brown powder.Relative density 3.125.Almost insoluble in water, slightly soluble in water with carbon dioxide.Soluble in dilute mineral acid, slightly soluble in ordinary organic acids, insoluble in alcohol and liquid ammonia.Stable in dry air.When wet, it’s easy for oxidation, manganese sesquioxide will be informed, gradually becoming dark brown, then emitting carbon dioxide by thermal decomposition.
Content of Mn
Solution shows pink,clear and transparent
This product, rosy triangle crystal or amorphous brown powder,, prevent moisture in the process of transportation, storage should be placed in a cool, ventilated, dry place. Avoid breathing dust when processing, if contamination, can be cleaned with soap and water , concrete technology may refer to the corresponding material safety data.
No.1 Manganese metal method
The manganese metal dissolved in nitric acid and then reaction. The heavy metals from the natural manganese nitrate solution are purified by hydrogen sulfide.After filtration, the purification liquid of manganese nitrate reacts with ammonium bicarbonate. The natural manganese carbonate, the precipitates are washed, filtered, dehydrated, dried and then High purity manganese carbonate, manganese carbonated feed grade, finished. chemical equation as follows,
No.2 double decomposition reaction method
Insolubles are filtered and removed by dissolved manganese sulfate with water or Steam at the top of the reactor. And then purified by hydrogen sulfide to remove the heavy metals and so on. Heating boiling, filtering, the pure manganese sulfate solution is finished. After double replacement reaction with ammonium hydrogen carbonate at 25℃~30℃ in the recator. The natural manganese carbonate, the precipitates are washed, filtered, dehydrated, hot wind dried at 80℃~90℃, manganese carbonated, finished. chemical equation as follows,
No.3 Pyrolusite method
Soft manganese ore powders mixed with pulverized coals, by reductive roasting and sulfuric acid leaching, then manganese sulfate solution finished, after filtered , neutralization with ammonium bicarbonate and again, then through vacuum filtration, dehydration and drying, manganese carbonate finished.The chemical equation as follows,
No.4 Rhodochrosite method,
Mixed sulfuric acid solution and rhodochrosite powders according to proportion and reaction, the natural manganese sulfate solution will be purified, divided, neutralization with ammonium bicarbonate and again,
then through vacuum filtration, dehydration and drying, manganese carbonate finished.The chemical equation as follows,
No.5 Manganese chloride method
To make low heavy metals manganese carbonate with chloride, manganese chloride could be made by the reaction of hydrochloric acid and manganese oxide or rhodochrosite. Also by the Manganese sulfate slag or other scraps with hydrochloric acid manganese salts.
under the premise of Manganese chloride solution in Ph ~ 5 , adding sodium sulfide to remove the heavy metals, and then adding the settlement agent for settlement, manganese chloride purification by filtration, put the solid ammonium hydrogen carbonate into the lution to make neutralization and reaction, through filtration, washing, drying,the low heavy metal content of manganese carbonate was finished.And after neutralization ,filtering the mother liquor to be the ammonium chloride solution, Through evaporating, crystallization, separation, drying the recycled ammonium chloride. The chemical equation as follows,
4.Shanghai liangjiang Titanium White Products Co.,Ltd,the market research for Manganese Carbonate.
At present, we have found manganese ore reserves was 688 million tons in China, annual consumption of manganese ore is 45 million tons in China, the world's largest consumers, 51% manganese ferroalloys, 42% manganese metals, 7% electrolytic manganese dioxide and others. Manganese carbonate is the ideal magnetic materials of high performance, which is widely used in electronic industry. also the main raw material of the soft magnets and other manganese salts, used in the production of the aluminum and manganese silicon alloys, used as fertilizers and feed additives, etc.
