The Mohs Scale of Hardness for Metals: Why It Is Important. Where a metal stands on the Mohs scale indicates which other metals can scratch it. For example, gold's hardness rating is 2.5-3, which is lower than that of most other metals.
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.

Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron.Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.
Mohs - Vickers hardness comparison: This chart compares the hardness of index minerals of the Mohs hardness scale (an integer scale) with their Vickers hardness (a continuous scale). Mohs hardness is a resistance to being scratched, while Vickers hardness is a resistance to indentation under pressure.

The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.
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.

A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory crushers can be used for primary or secondary crushing. The crushing action is caused by the closing of the gap ...

The Egyptians and Romans used manganese compounds in glass-making, to either remove color from glass or add color to it. Manganese can be found in the iron ores used by the Spartans. Some speculate that the exceptional hardness of Spartan steels derives from the inadvertent production of an iron-manganese alloy.
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.
Tungsten, Cobalt, and More on Mohs Scale of Mineral Hardness A mineral is traditionally defined as a compound that is solid, and which is found primarily in nature. While there are a number of ways in which minerals can be studied, their degree of hardness being one of them.
