All ores are minerals ;but all minerals are not ores . Why?
Dear student
All ores are the minerals from which metals can be extracted commercially but all the minerals cannot be used to extract any metals e.g. bauxite is an ore of aluminium metal.
Aluminium occurs in earth's crust in the form of two minerals bauxite and clay. Out of these, aluminium can be easily and profitably extracted from bauxite only. So, we can infer that bauxite is an ore of aluminium.On the other hand, it has not been possible to obtain aluminium from clay by some easy and cheap method. So, clay remains only as mineral and not as ore of aluminium.
