Classification of Minerals. Minerals have been broadly classified into two classes, primary minerals and secondary minerals. Minerals which were formed by igneous process that is from the cooling down of the molten materials called magma, have been put in the primary category, while those formed by other processes have been put in the secondary category.
Hardness is how resistant a mineral is to scratching, not how easily it breaks.Hardness depends on the bonds within the mineral, so the stronger the bonds, the harder the mineral. Mineral hardness is measured on the Mohs scale of hardness, which compares the hardness of different minerals.. Diamond is considered the hardest mineral, so it's a 10 on the Mohs scale of hardness.
