There are 3000 different kinds of Minerals and depending on their composition, they can be characterized into metallic and non-metallic minerals.
Metallic minerals contain metal in the raw structure. Iron metal, bauxite, manganese metal are a few examples of metals. Metallic minerals might be ferrous or non-ferrous. Ferrous minerals like iron metal, manganese and chromite contain iron. A non-ferrous mineral doesn't contain iron, however, may contain some other metal, for example, gold, silver, copper or lead.
Non-metallic minerals don't contain metals. Limestone, mica and gypsum are instances of such minerals. Fuels like coal and oil are likewise non-metallic minerals. Minerals can be removed by mining or quarrying.
