"The concentration of a pyrolusite ore" by Frank O. Blake

"This is the history of an attempt to produce from a pyrolusite ore, a material sufficiently rich in manganese to be of value in the various industries such as the making of speigeleisen and ferro-manganese, the glass manufacturing, and the chemical industries. The greater part of the manganese used in the United States comes from Brazil, India and Russia.

Pyrolusite Wikipedia

Pyrolusite is a mineral consisting essentially of manganese dioxide (Mn O 2) and is important as an ore of manganese. It is a black, amorphous appearing mineral, often with a granular, fibrous, or columnar structure, sometimes forming reniform crusts. It has a metallic luster, a black or bluish-black streak, and readily soils the fingers.The specific gravity is about 4.8.

Pyrolusite Mineralogy4Kids

Pyrolusite. One of the most common manganese ore minerals, pyrolusite is used in making steel. It is widespread in its occurrence, forming in lacustrine, shallow marine, and bog deposits. It was named in 1827 from the Greek word for "fire" and "to wash" because it was used to remove brown and green tints in the making of glass. Mineral Photos courtesy of R.Weller/Cochise College.

Manganese Wikipedia

The most important manganese ore is pyrolusite (MnO 2). Although Mn concentrations at or below 300 µg Mn/L were considered safe at the time of the study by the US EPA and 400 µg Mn/L by the World Health Organization, the 92 children sampled (between 11 and 13 years of age) from this province displayed lower performance on tests of manual dexterity and rapidity, short-term memory, and

Concentration of ore simply.science

Iron ores like magnetite, chromite and manganese ore like pyrolusite are concentrated by this process. Sometimes, a reverse situation may occur: the ore is non magnetic and the gangue is magnetic. In this case also magnetic separation may be used for concentration of the non magnetic ore. Bayer's process Bayers process is the most economic means of obtaining bauxite. Two to three tonnes of
