About boron nitride
Ferromanganese is not something produced from nature. It is a alloy produced from manganese ore and coke.
You are probably aware that iron ore is a raw material of iron. However, it takes more than just iron ore to make iron (steel). There are various "sub-materials" that are required. In the manufacture of steel, ferromanganese serves as both a deoxidizer and a desulfurizering agent.
Depending on the percentage of carbon (carbon content), ferromanganese can be categorized into different groups: high-carbon, medium-carbon and low-carbon ferromanganese. These are used by different steel manufacturers for different purposes.
Ferromanganese is made by feeding manganese ore and coke into intense heat in a shaft furnace (the interior temperature of the shaft reaching 2600°C). When in the shaft, the manganese ore is reduced in line with the amount of carbon present, thus causing its manganese element to be extracted.
