The material of ferrite for electrical equipment, Industrial
Manganous Carbonate used as catalyst, pigment, drier, the material
of manganous salts, or used in medicine, mechanical parts and
phosphating process. It also can be used in the fertilizer as track
rosy rhombus crystal or formless light brown powder , relative
density 3.125 .almost insoluble in water, but slightly soluble in
water containing CO2. Soluble in dilute inorganic acid, slightly
soluble in common organic salt, insoluble in liquid ammonia. Stable
in dry air, wet easily oxidized to form manganese oxide gradually
becomes black, heated hours of the liberation of the CO2, when
water is azeotropic hydrolysis. The boiling potassium hydroxide,
the formation of manganese hydroxide.

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.
Packing : 25kg in plastic woven bag.
Storage : Normal chemical, stored in cool, dry and airiness place,
avoid moisture, heat and decay . In transportation, avoid rain and
sunlight. Load gently, no breakage. If fire, fight it with water,
sand and fire fight machine.
