An ore is any naturally-occurring source of a metal that you can economically extract the metal from. Aluminium, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals. However, it isn't economically worthwhile to extract it from most of these minerals. Instead, the usual ore of aluminium is bauxite

A metal ore is a rock that contains enough of the metal to make it worthwhile extracting. They have to be extracted from their ores through processes such as electrolysis, using a blast furnace or by reacting with more reactive material. In many cases the ore is an oxide of the metal, therefore the extraction of these metals is a reduction
