Shanghai Yue Jiang titanium white chemical products Co., Ltd.   

Yue Jiang brand manganese carbonate (industrial grade) adopts the direct acidizing method of soft manganese ore powder (i.e. the two ore method), calcined pyrolusite to oxidize manganese and then acidification, reducing the calcining process, greatly saving equipment investment, reducing environmental pollution and reducing the cost. The product is rosy trigonal crystal rhombohedron or amorphous bright white brown powder. The specific gravity is 3.125, almost insoluble in water, but slightly soluble in water containing CO2. Soluble in dilute inorganic acid, slightly soluble in common organic acid salts, insoluble in liquid ammonia. It is easy to oxidize in dry air when it is stable and humid. It forms three oxidized two manganese and gradually becomes black. When heated, it decomposes and releases CO2 and boiling with water.
