Preparation of high-purity manganese carbonate by leaching manganese ore with sulfur dioxide;

A study on prepapation of high-purity manganese carbonate from mangeniferous weste water;

As to the problem that the electrolytic manganese anode solution produced from the absorption solution of wet flue gas desulfurization with pyrolusite pulp can't be recycled,we think this topic is on obtaining high-purity manganese carbonate form the electrolytic manganese anode solution through removing the impuritity,carbonization crystallizing,removing calcium,natrium,and sulphate.

Development of high purity manganese carbonate from low-grade manganese oxidized ore;

After reduction , manganese is extracted by sulfuric acid and high purity manganese carbonate is obtained after impurity removal from the solution and reaction with ammo.

The technology that high purity manganese carbonate is gained by precipitation from homogeneous solution , manganese minerals used as materials, is studied in this article .

Distillation separation-IC determination of trace amount of chloride and nitrate in high purity sulfuric acid;

this paper introduces the production principles and methods of high-purity magnesium sulfate,and expounds its application in the aspects of foodt,health care,clinic,veterinary,and chemical reagent,etc.
