manganese processing
Manganese.
After manganese is deposited onto stainless-steel cathode sheets in an electrolytic cell and subsequently removed by hammering, the resulting flakes are heated to 500 °C (925 °F). This heating process is performed to remove hydrogen from the metal, which results in a powdered manganese product with a purity level exceeding 99.9 percent.1
