How can one extract manganese from manganese oxide?

Metallic manganese was first isolated in 1774 by Johan Gottlieb Gahn, a Swedish mineralogist who reduced pyrolusite, a manganese dioxide ore, with carbon. .... agent carries over to the final ferromanganese product—about 1 percent when silicomanganese is used and 0.1 percent with low-carbon silicomanganese. read more

The higher oxides (MnO 2, Mn 2 O 3, and Mn 3 O 4) can all be reduced to manganous oxide (MnO) by carbon monoxide, but this lower oxide can be reduced to the metal only at elevated temperatures by carbon. read more

Making your own explosives is fun stuff, but getting the many different materials that you need can be tricky. This video will show you how to extract Manganese Dioxide from alkaline batteries, which you can then combine with hydrogen peroxide to create oxygen gas, which is very explosive indeed. read more

Ammonium salts, such as (NH 4) 2 SO 4 or NH 4 Cl, are also used to convert manganese oxides into water soluble forms (Sahoo and Rao, 1989). Sulfur-based reduction of manganese oxide ore has received increasing attention . read more
