Manganese.
In the process of refining manganese, hydrogen sulfide is added to a manganous sulfate solution to remove specific impurities through precipitation. The metals and elements removed during this stage are:
- Arsenic1
- Copper1
- Zinc1
- Lead1
- Cobalt1
- Molybdenum1
Once these contaminants are precipitated and removed, the remaining purified solution is processed in an electrolytic cell to produce high-purity manganese.1
