manganese ore physical properties

Manganite Physical Optical Properties, Uses, Occurrence

An important ore of manganese, manganite occurs in hydrothermal deposits formed at low temperature (up to 400176;F/200176;C) with calcite, siderite, and barite, and in replacement deposits with goethite. Manganite also occurs in hot spring manganese deposits.

The Properties and Effects of Manganese as an Alloying Element

Properties of Manganese Alloys. Silicomanganese alloy contains 65 to 68% manganese, 16 to 21% silicon, and 1.5 to 2% carbon, and is generated by the smelting of slag from manganese ore or high carbon ferromanganese with a quartz flux and coke. The alloys carbon content is reduced due to the presence of silicon.
