Amazing Material Electrolytic Manganese Flake

The special production method of electrolytic manganese flakes mainly includes the use of silica manganese slag instead of manganese carbonate ore for multi-stage leaching. The key steps in this method include: First-stage leaching: an anode solution sufficient to react the material is injected into the compounding tank, followed by the addition of concentrated sulfuric acid and silicon-manganese slag.Subsequent leaching: After each stage of leaching, the filtrate after the leaching press of the upper stage is injected into the chemical tank, and then the anode solution is supplemented, and concentrated sulfuric acid and silicon-manganese slag are added.

1.By electrolytic manganese flakes, the Mn2+ in the slag can be extracted and turned into manganese sulfate into solution. After reaching the manganese concentration required by electrolysis, the processes of iron removal, silicon removal, neutralization, purification, and electrolysis are carried out sequentially, and finally qualified electrolytic manganese metal is obtained. This method not only solves the problem of unstable mineral sources, but also greatly reduces production costs, improves competitiveness, and solves the environmental protection problem that the waste residue produced in the production of silicon-manganese is difficult to dispose of, forming a circular economy.The following points need to be paid attention to when using electrolytic manganese tablets: Impurity control: In the production process, some harmful impurities will inevitably be generated, such as metal impurities (such as iron and heavy metal nickel), organic impurities, etc. These impurities need to be removed by specific methods, such as iron removal by oxidative hydrolysis, heavy metal nickel by sulfiding agent precipitation, and organic impurities by adsorption methods such as activated carbon.
