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

The performance index of manganese carbonate (feed grade): Yue Jiang brand manganese carbonate (feed grade) is directly acidified by soft manganese ore powder (i.e. two ore method), pyrolusite is calcined into manganese oxide and acidified, which reduces the calcining process, greatly saves equipment investment, reduces environmental pollution and reduces costs. 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. In dry air, it is easy to oxidize when it is stable and humid, forming three oxidation of two manganese and gradually becoming black.
