Manganese powder: The manganese ore excavated from the mine is ground into powder by grinding machinery, which is "manganese powder". This is physical processing, and the chemical properties of the manganese ore have not changed.
Electrolytic manganese: Manganese metal obtained by electrolysis after treating manganese powder with chemical raw materials such as sulfuric acid is called "electrolytic manganese", which is chemical processing. Manganese compounds such as manganese carbonate in manganese ore become metal manganese.
As a common name, "manganese powder" can refer to the powder made from manganese ore factory or the powder made from electrolytic manganese flakes.
