hardness of manganese ore

Microhardness characterisation of manganese ore

2020-10-1  Manganese ore mineral chemistry is compositionally and texturally complex, partly because manganese can be present in the divalent, trivalent or tetravalent states, but also because other elements are also frequently present (e.g., K, Na, Fe, Mg, Al, Si and Ba) . The extent to which the presence of other element impurities in manganese ore minerals might affect their microhardness is complex, as published microhardness data for common Mn ore
