  • Bauxite My rock family

    Bauxite is usually extracted from the ground using a form of mining called strip mining, as it is found near the surface of the earth. This involves scraping away layers of the earth to reach ore bodies close to the surface. This type of mining can pollute waterways and destroy landscapes. Strip mining produces a lot of excess sediment.
