India's bauxite exports are predicted to grow at an average rate of 3.33% from 2023 to 2027. Aluminium Ore. Bauxite is the main ore for aluminum, with nearly all aluminum produced from it. Bauxite is not a mineral it's a rock made mostly of aluminum-bearing minerals and forms when laterite soils lose silica in wet climates.
