AnswerClick to flip back
A
bauxite
💡 Explanation:
Bauxite is the correct answer because it is the principal ore of aluminum that exists in hydrated forms in nature. Bauxite contains aluminum hydroxide minerals like gibbsite (Al(OH)3), boehmite (AlO(OH)), and diaspore (AlO(OH)), which are all hydrated forms of aluminum oxide. Haematite (Fe2O3), carbonates, and sulphides are not typically found as hydrated ores.
