It was discovered 1774 by Johann Gahn. Manganese easily reacts with water and air. 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
What is Mohs Hardness Scale? One of the most important tests for identifying mineral specimens is the Mohs Hardness Test. This test compares the resistance of a mineral to being scratched by ten reference minerals known as the Mohs Hardness Scale (see table at left). The test is useful because most specimens of a given mineral are very close to the same hardness.

Mohs' scale of mineral hardness is named after Friedrich Mohs, a mineralogist.Mohs scale is ordered by hardness, determined by which minerals can scratch other minerals.. Rocks are made up of one or more minerals. According to the scale, Talc is the softest: it can be scratched by all other materials. Gypsum is harder: it can scratch talc but not calcite, which is even harder.

Mohs hardness test. The Mohs hardness test is one of the earliest attempts at defining and comparing the hardness of mineral materials. The Mohs scale consists of values from 1 to 10, which correlate with the ability of the test material to withstand scratching by progressively harder minerals. It is typically used for geological purposes.

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.
