Preparation of Pure Manganese Metal

Manganese metal was first produced by an aluminothermic process in 1898 (see History). Some commercial production took place in the early 20th century. At present, two major techniques are used industrially to produce pure manganese metal on a large commercial [Pg.153]

Parameters Anode material Cathode materials Diaphragm [Pg.155]

Operating temperature Anodic current density Cathodic current density Cell voltage Faradic efficiency [Pg.155]

Pb-Agor Pb-Ca, DSA-IrOj Stainless steel or titanium Polymer fabric MnSO, 4wt.% [Pg.155]

The major producers of electrolytic manganese worlwide are Erachem Comilog and Kerr-McGee Chemical in the United States, the Manganese Metal Company (MMC) in the Republic of South Africa, and finally Mitsui Mining Smelting and Tosoh in Japan. [Pg.155]
