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 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?


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.

?

3. 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& acute;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!

4.?Applications:

No.1 Using in the production of manganese salts, also used as the materials of telecommunication components.

No.2 ?Used in the desulfurization catalysts, enamel paint, manganese salt ,also used in fertilizers, medicine, feed additives, electrode materials etc
No.3? Used as the materials of soft magnetic ferrite in telecommunication components. Manganese carbonate industrial grade is widely used in the desulfurization catalyst, enamel paint, varnish, drier and the raw materials other manganese salts.Also used in medicine, mechanical parts and phosphating treatments, etc. If used in trace element fertilizers, its content can be slightly lower.

No.4? Used in the magnetic materials of communication equipments, the high performance manganese zinc ferrite.

No.5 Using in the production of manganese salt, widely used in the desulfurization catalyst, enamel paint, varnish, drier and the raw materials other manganese salts.Also used in medicine, mechanical parts and phosphating treatments, etc
