MANG ANESE, MAN GANESE DIOXIDE, FERR OMAN …

Exhibit 6 depicts a typical production process of manganese metal from ore. Manganese ore is roasted to reduce the higher oxides to manganese (II) oxide. Slag from the production of high carbon ferromanganese may also supply manganese (II) oxide. The reduced ore or slag is leached with sulfuric acid to produce manganese (II ) sulfate.
