Brief introduction of producing method : Pyrolusite powder direct acidification method (two-mine method)

1, Chemical combination method : It can save investment and reduce pollution and cost because this method cut the calcination process.2, Main materials : pyrolusite and pyrite react with vitriol, and then remove the impurities to get manganese sulfate solution, which react with ammonium bicarbonate to produce Manganese carbonate.


1,The material of ferrite for electrical equipment

2,Industrial Manganous Carbonate used as catalyst, pigment, drier, the material of manganous salts

3,Used in medicine, mechanical parts and phosphating process

4,It also can be used in the fertilizer as track element.



Paccking Storage &Transportation

1,25kg in plastic woven bag lined with double-layer high pressure polyethylene bag.

2,Normal chemical, stored in cool, dry and airiness place, avoid moisture, heat and decay .

3,In transportation, avoid rain and sunlight. Load gently, no breakage.

4, If fire, fight it with water, sand and fire fight machine
