There are many uses of industrial-grade manganese carbonate. It is a raw material for the manufacture of telecommunications equipment soft magnet oxygen, the synthesis of manganese dioxide and the manufacture of other manganese salts. Used as a catalyst for desulphurization, enamel, paint and varnish pigments. It is also used as a fertilizer and feed additive. Used for medicine, welding rod accessories, etc.. Many manufacturers will also choose industrial manganese carbonate to produce manganese nitrate.

There are several kinds of manganese nitrate production processes, one of which is: the reaction with nitric acid using pyromanganese ore or diamond manganese ore, purified and mixed, concentrated and crystallized, and using industrial manganese carbonate or manganese hydroxide as raw material. Simplified operation. Used as a fertilizer and colorant. The advantage of this method, using ammonia and carbon dioxide, is that the by-product ammonium nitrate is also a useful fertilizer.

Industrial manganese nitrate is usually 50 % liquid manganese nitrate, light red or rose-colored transparent liquid, relative density 1.54(20 °C), soluble in water and alcohol, heated to precipitate manganese dioxide and emit nitrogen oxide gas, easy to oxidize in the air. Solid manganese nitrate is usually a light rose-colored needle diamond crystal. It has several forms of water, one water, three water, four water, and six water. The melting point is 25.8 °C, the boiling point is 129.5 °C, and the density is 1.82 g/cm3(21 °C, six water), 1.9 g/cm3(21 °C, four waters), soluble in water and alcohol, decomposed at 160 ~ 200 °C to form manganese dioxide, deliquescent, easy to oxidize. High-purity manganese nitrate is characterized by high purity, high density, and density & GT; 1.9 g/cm3, good stability, at a constant temperature of 65 °C, the product does not blacken for 72 hours without precipitation.

Therefore,the requirement for raw material manganese carbonate is very high,after 1-7 days phosphoric acid test , there is no obvious precipitate in the solution, which means that the requirement for phosphoric acid insoluble substances is particularly high.

Ordinary industrial manganese carbonate can not meet this requirements.Our company can be customized for high-purity manganese nitrate production of manganese carbonate according to customer requirements, because it is customized production, the price will of course be a little more expensive than ordinary industrial grade manganese carbonate, welcome to telephone consultation.
