Question

Write the chemical names of aluminum ores with their formulae.

Answer 1

• The mineral from which the metals can be extracted commercially at low cost and with minimum effort is known as ores.
• Aluminium is extracted from the Bauxite $({\mathrm{Al}}_2{\mathrm{O}}_3.2{\mathrm{H}}_2\mathrm{O})$, cryolite $\left({\mathrm{Na}}_3{\mathrm{AlF}}_6\right)$, or corundum $\left({\mathrm{Al}}_2{\mathrm{O}}_3\right)$ ore.

Ore	Chemical name and formula
Bauxite	Hydrated aluminum oxide, ${\mathrm{Al}}_2{\mathrm{O}}_3.2{\mathrm{H}}_2\mathrm{O}$
Cryolite	Sodium aluminum fluoride, ${\mathrm{Na}}_3{\mathrm{AlF}}_6$
Corundum	Anhydrous aluminum oxide, ${\mathrm{Al}}_2{\mathrm{O}}_3$
