Manganese is a transition metal with important industrial alloy uses, particularly in stainless steels. Historically, manganese is named for pyrolusite and other black minerals from the region of Magnesia in Greece, which also gave its name to magnesium and the iron ore magnetite.
Aug 23, 2019· On Earth, manganese is never found as a free metal, but it is found in a number of minerals. The most important of these minerals is pyrolusite, the main ore mineral for manganese. Manganese is essential to iron and steel production. The U.S., Japan, and Western Europe are all nearly deficient in economically mineable manganese.
The Mohs scale of hardness can be useful when you are shopping and debating between pieces of jewelry made from different metals. By looking them up in the metals hardness table, you can see which option will give you better durability, and you can then decide if the price asked for it is worth it to you.

AR400 or AR500 steel for liners, rotors, and screens, and maybe a chrome alloy for the hammers. Based on the Mohs rating I would think the mill would work okay, but that the wear parts would be worn out prematurely. I've seen standard steel or manganese steel hammers last about 30-50% of the life of chrome hammers with quartz ore, for example.
