Question

Distinguish between a mineral and an ore; an ore and a metallic compound.

Answer 1

Difference between a mineral and an ore:

Mineral	Ore
Minerals are naturally occurring inorganic solids with a crystalline structure, which contains metals in the combined state along with earthly impurities.	Ores are concentrations of minerals in rock that are high enough to be economically extracted for use.
All minerals are not ore.	All ores are minerals.
For example, Quartz is a mineral found in granite rock.	For example, Bauxite $({\mathrm{Al}}_2{\mathrm{O}}_3.2{\mathrm{H}}_2\mathrm{O})$ is an ore of aluminium.

Difference between an ore and a metallic compound:

Ore	Metallic compound
Ores are concentrations of minerals in rock that are high enough to be economically extracted for use. Metallic compounds are extracted from ore at comparatively less cost and effort.	A metallic compound is a compound that contains one or more metal elements bonded to other elements. The metal atom acts as the cation in the compound and is bonded to a non-metallic anion.
Ores occur naturally in nature.	Metallic compounds are man-made.
For example, Bauxite $({\mathrm{Al}}_2{\mathrm{O}}_3.2{\mathrm{H}}_2\mathrm{O})$ is an ore of aluminium.	For example, calcium chloride $\left({\mathrm{CaCl}}_2\right)$ is a metallic compound having ${\mathrm{Ca}}^{+}$ cation and ${\mathrm{Cl}}^{-}$anion.
