Physical and Chemical Properties. Rhodochrosite has a variable chemical composition. It is a manganese carbonate, but the manganese is frequently replaced by iron, magnesium and/or calcium as shown in this formula (Mn,Fe,Mg,Ca)CO 3.. These substitutions of other elements for manganese change the composition and alter the specific gravity, hardness, and color of the mineral.
Mar 12, 2019 Manganese is an extremely brittle and hard, silvery-grey metal. The twelfth most abundant element in the earths crust, manganese increases strength, hardness and wear resistance when alloyed in steel. It is Manganeses ability to readily combine with sulfur and oxygen, which makes it critical in the production of steel.
Rhodonite is a pink manganese silicate mineral of variable composition that often contains significant amounts of iron, magnesium, and calcium. It has a generalized chemical composition of (Mn,Fe,Mg,Ca)SiO 3. Rhodonite is often associated with black manganese oxides which may occur as dendrites, fracture-fillings, or matrix within the specimen.
Rhodochrosite, a carbonate ore, is one of the most important Manganese ores (8). Mining for Manganese ore is generally done in open pits. Pure Manganese is produced by hydrometallurgical and electrolytic processes (8). Manganese is rarely used by itself due to its natural hardness. It is used in various metallic alloys, one such alloy is steel (3).

Manganese. Manganese (element 25, symbol Mn) is a gray-white metal with a pinkish tinge, and is very brittle, but hard. 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
The Mohs hardness is estimated to be 5 as tested on the specimen by apatite and orthoclase standards, and the streak is red. The measured density by the method of flotation in heavy liquids is 2.83(3) g/cm 3 , which is in good agreement with the calculated density of 2.86 g/cm 3 .
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. Ive seen standard steel or manganese steel hammers last about 30-50% of the life of chrome hammers with quartz ore, for example.
