Manganese Ore - an overview ScienceDirect Topics

Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use manganese ore fines in sinter productions. This would ensure much more consistent manganese content in the hot metal.

Manganese: applications and uses-Metalpedia

Manganese dioxide is used in drying black paints and in the preparation of oxygen and chlorine. It also acts as a catalyst in the production of artificial flavors like vanilla and as an oxidizing agent in treating uranium ore to produce the oxide-concentrate. Manganese compounds have also been used in the coloring of ceramics and glass.

Corrosion Monitoring Of Produced Waters PETSOC

Although manganese counts are currently a popular method of monitoring corrosion, there are some difficulties associated with their use as well. First of all, it is possible to obtain very low observed values of manganese in oilfield waters. Ranges from 2 ppm manganese down to 0.002 ppm manganese for produced waters are entirely possible.

All natural manganese is the stable isotope manganese-55. It exists in four allotropic modifications; the complex cubic structure of the so-called alpha phase is the form stable at ordinary temperatures. Manganese somewhat resembles iron in general chemical activity. The metal oxidizes superficially in air and rusts in moist air. It burns in air or oxygen at elevated temperatures, as does iron ...
