Description:

1, Liangjiang Brand – feed grade manganese carbonate, adopt manganese powder as raw material to roast. Compared with rhodochrosite and pyrolusite, it is much easier, lower impurities content, less harmful heavy metal. This product is rosiness, prismatic crystals or amorphism white and brown powder. Relative density 3.125. Almost insoluble in water. Slight soluble in water contains carbon dioxide. Soluble in diluted mineral acid, slight soluble in organic acids, insoluble in alcohol and liquid ammonia.

It is stable in dry air. Easy oxidation to manganese oxide when damped, become brownish black, release carbon dioxide when heated.

Main uses: Manganese carbonate, produced by Shanghai Liangjiang titanium white product co., widely used in manure, medicine, machine parts and Parkerizing.

2, Liangjiang Brand – feed grade manganese carbonate, adopt manganese powder as raw material. This method can well-adapt with raw materials, good edulcoration effect. After dislodge iron and other heavy metal, washing-up sulfate, then drying, smashing to get feed grade manganese carbonate.

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↑?

1. Shanghai liangjiang Titanium White Products Co.,Ltd, the market research for feed grade Manganese Carbonate.

? In China, there are more than 500 factories are occupied in producing feed grade mineral element and complex. There into, about 80 middle and small sized factories produce manganese carbonate feed grade. Feed grade manganese carbonate share about 10% market in feed grade raw material. Annual output is about 220 thousand tons. Apart from China, there are about 10 factories of feed grade manganese carbonate are located on India, South Africa, American, Mexico. In recent years, China& acute;s neighboring countries and regions usage amount of feed grade manganese carbonate is about 1,500,000 tons per year in total. Most of these products are imported from China.

The rapid development of China& acute;s feed additive industry, greatly promoted the rapid development of China& acute;s feed production processing industry, also pull the feed product market competition.

?

2. 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& acute;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 carbonate will continue to rise.
