PYROLUSITE Manganese Oxide Amethyst GalleriesAustralian Resources Manganese Ore MiningLink The

Pyrolusite is the most common manganese mineral and is an important ore Manganese is a strategically valuable metal since it is an essential ingredient in steel and other alloys The mining term wad is used to indicate ores that are a mixture of several manganese oxides such as pyrolusite Manganese ore is notable because of its silver grey metal colour with a pinkish tinge about it It is quite hard while at the same time reasonably brittle Manganese ore is commonly found in sedimentary deposits or in metamorphic rocks The most common ore mineral to contain manganese is pyrolusite
