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, it’s 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.
3, Liangjiang brand- manganese carbonate production process:
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,
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.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.
we aspires to be the supplier of the world's leading chemical raw materials, show our value of the products made in China!
