Rech Chemical Co. Ltd teach you how to determine the quality of manganes sulphate monohydrate
Manganese sulfate monohydrate manufacturer can produce high quality products,which can be judge from the necessary raw materials, production process and production management services inspection. How to identify the pros and cons of manganese sulfate monohydrate? Please check Rech Chemical analysis from the following aspects.
Production of raw materials: the production of feed-grade manganese sulfate pyrolusite main raw material containing Mn 20% ~ 25% is appropriate; manganese 15% to 20% of manganese ore to make compliance, will increase the relative cost.But the final product will have low content of Mn. Therefore,when choosing raw materials,manufacturers should pay attention to pyrolusite Ca content. If the impurities Ca content is high, it will increase the acid consumption;At the same time, the content of Mg is need strictly controlled at 0.5% or less, because the solubility of MgSO4 and MnSO4 as difficult to separate.
Production process: two low-grade pyrolusite ore leaching method principle and under certain conditions for direct pyrite leaching with sulfuric acid reducing the Mn content is about 25% of low-grade manganese ore leaching rate of 93%. The process will the same as the follow pictures.
Production site management: site management confusion, outdated equipment of enterprises will not produce high-quality, stable feed-grade manganese sulfate product.
