    CAS 598-62-9 Industrial Grade Manganese Carbonate MnCo3 Amorphous Brown Powder

    Shanghai Liangjiang Titanium White Product Co., Ltd.


    CAS No.598-62-9 Industrial grade Manganese carbonate MnCo3


    1,Liangjiang brand- manganese carbonate industrial grade, 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, its easy for oxidation, manganese sesquioxide will be informed, gradually becoming dark brown, then emitting carbon dioxide by thermal decomposition.

    Application:

    Shanghai Liangjiang titanium white products co., LTD. Production of manganese carbonate is widely used in telecommunications equipment is used as the material of ferrite, desulfurization catalyst, enamel paint, varnish drier, manganese salt catalyst manufacture and raw materials.In fertilizer, medicine, machinery parts, and also need to use the manganese carbonate in phosphating treatment.Agricultural use manganese carbonate as trace element fertilizer its content can be slightly lower.

    2,The main raw materials of Liangjiang-brand industry grade Manganese carbonate are pyrolusite and pyritic. The two materials reacted with sulfuric acid, and through the process deironing, wiping off other heavy metals to get manganese sulfate solution. Then neutralize the solution with ammonium bicarbonate to get final manganese carbonate products.


    The manganese carbonate production methods at present including four kinds of technique:

    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,

    Mn+4HN03→Mn(NO3)2+2NO2+2H2O

    Mn(NO3)2+2NH4HCO3→MnCO3↓+2NH4NO3+CO2↑+H2O

    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,

    MnSO4+2NH4HCO3→MnCO3↓+(NH4)2SO4+CO2↑+H2O


    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,

    MnO2+C→MnO+COMnO2+CO→MnO+CO2↑

    MnO+H2SO4→MnSO4+H2O
    MnSO4+2NH4HCO3→MnCO3+(NH4)2SO4+CO2↑+H2O

    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,

    MnCO3+H2SO4→MnSO4+CO2+H2O
    MnSO4+2NH4HCO3→MnCO3+(NH4)2SO4+CO2↑+H2O

    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,

    MnC12+2NH4HCO3→MnCO3+2NH4Cl+H2O+CO2↑

    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. With the expansion of downstream demand for the manganese carbonate industry, the development of manganese carbo

    nate will continue to rise.

    5.Shanghai Liangjiang Titanium white Products Co.,Ltd, the brand building for Manganese Carbonate:
    It is a not long history for Manganese carbonate industry in china, so far many enterprises haven’t woken up for brand awareness., the brand strategy has not been formed and not adopted, It has been a rapid development, so that less brand enterprise of manganese carbonate, less well-known brands.The brand construction is particularly important, An increasing number of enterprises of manganese carbonate is paying more and more attention to the brand.Reality tells us that whether state-owned enterprises, or corporation; Whether individual breakthrough, or advancement, if they the want to narrow the gap with foreign, to improve the brand awareness, brand construction, brand building, brand promotion and brand marketing, to strengthen China's manganese carbonate industry brand effects,to improve the manganese carbonate enterprise brand value.Therefore Shanghai liang jiang titanium white products co., LTD., based on quality, quality, market analysis and so on, to promote domestic and international markets, to increase the popularity of manganese carbonate made by shanghai liangjiang titanium white products co.,ltd in domestic and foreign markets, do the best quality,show our value of the products made in China!
