Purification of hydroquinone by-product manganese sulfate;

A study on preparation of manganese sulfate with low grade manganese ore;

Research and industrial application for new technology of manganese sulphate;

Study on the leaching toxicity and safe disposal of manganese sulphate waste residue;

Further treatment purification and crystallization are taken to fabricate manganese sulphate, The quality of manganese sulphate reaches the level of national standard(GB1622-86).

By curing process,and used pyrite,pyrolusite and sulfuric acid as material,manganous sulfate was product.

A analytic method was developed for determination of calcium in manganous sulfate by AAS, using air-ethyne flame, adding strontium salt restraint disturbance, the results showed that the method was suitable.

This artical introduces the effective practical new technique and it' s process for desulfurizing with pyrolusite slurry and the by-product recovery of manganous sulfate.

These are two ways of preparing Mn3O4 by MnSO4 directly.

The effects of adding of MnSO4 on the deposition rate, the structure and the magnetic performances of the Co-Fe-P deposit were investigated by scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and vibrating sample magnetometer (VSM).

In this paper,a new method to prepare MnSO4 from Zn-Mn battery is introduced.

Study on the removing of MgSO_4 from MnSO_4 solution based on the aqueous system phase diagram;

What the paper tells about is to take rich-manganese-slag as raw material,leaching it through sulfuric acid and producing manganese sulphate solution,which is applied in the production of electronic manganese.
