Therefore, the iron and steel industry is the main consumer of manganese ore in the country. About 10 kilograms of BFgrade manganese ore (2830% Mn) is required per ton of iron produced in Blast ...
It is commonly obtained through manganese ore in the form of manganese oxide (also known as pyrolusite), or through iron ores. Manganese production is thus often subsumed under iron mining. Besides their ores being regularly obtained from the same mines, manganese and iron are further linked due to their complementarity in steel production.

Because the density of manganese oxide ore such as pyrolusite, pyrolusite, and brown manganese ore is about 4g/m³, which is significantly different from the density of silicate gangue, most of them can use gravity separation. Manganese carbonate ore mostly adopts the combined process of dense medium and strong magnetic separation.
The Manganese Mining Process More than 25 million tons of manganese are mined every year. Most manganese mining occurs in open pits. Although there are processes in place to mine manganese nodules in the ocean floor, they cannot complete with landbased mining production.
While cooling from the molten state down to 1,138 °C (2,080 °F), it solidifies into a bodycentred cubic structure called the delta ( δ) phase; from that point down to 1,100 °C (2,000 °F) it is in the facecentred cubic gamma ( γ) phase, and from this point down to room temperature it goes through the beta ( β) and alpha ( α) phases.
