Manganese - Wikipedia

In the 16th century, manganese dioxide was called manganesum (note the two Ns instead of one) by glassmakers, possibly as a corruption and concatenation of two words, since alchemists and glassmakers eventually had to differentiate a magnesia nigra (the black ore) from magnesia alba (a white ore…

Manganese: Nodules, Uses, Facts, Ore, Alloys, Metal

Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy, it decreases the brittleness of steel and imparts strength. The amount of manganese used per ton of steel is rather small, ranging from 6 to 9 kilograms.

What are manganese ore fines and how are they sintered?

Fines are the fine particles of manganese ore created when crushing manganese rocks. The fines are heated to sinter them (make them stick together, or become "agglomerated"). "The mines produce a lot of fines," Hockaday explained. "But they can't sell them, as furnaces won't buy materials that are too fine.".
