Question

Explain the difference between ores and minerals?

Answer 1

Difference between ores and minerals:

Minerals	Ores
The natural substances in which metals or their compounds occur either in native sate or combined state are called minerals.	The mineral from which the metal can be conveniently and profitably extracted, is called an ore.
Example: Aluminium ($\mathrm{Al}$) occurs in the earth's crust in two different forms and they are, Bauxite (${\mathrm{Al}}_2{\mathrm{O}}_3.2{\mathrm{H}}_2\mathrm{O}$) and clay (${\mathrm{Al}}_2{\mathrm{O}}_3.2{\mathrm{SiO}}_2.2{\mathrm{H}}_2\mathrm{O}$).	Example: Aluminium ($\mathrm{Al}$) can be conveniently and profitably extracted from Bauxite (${\mathrm{Al}}_2{\mathrm{O}}_3.2{\mathrm{H}}_2\mathrm{O}$). So, Bauxite (${\mathrm{Al}}_2{\mathrm{O}}_3.2{\mathrm{H}}_2\mathrm{O}$) is an ore of Aluminium ($\mathrm{Al}$).
