Is aluminum foil bad for environment?What is bauxite mining used for? – AnswersToAllThe bauxite layer beneath the overburden is broken up using methods such a blasting, drilling and ripping with very large bulldozers. Once the bauxite is loosened into manageable pieces it is generally loaded into trucks, railroad cars or conveyors and transported to crushing and washing plants or to stockpiles, before being shipped to alumina refineries, which are generally located close to bauxite mines.Mining and Refining – Process

Bauxite Mining in the Boké Region (Western Guinea):

Bauxite mining does not require tunnels as digging gold mining or other mineral ores. However, it still requires heavy digging equipment and generates tremendous dust that pollutes the surrounding areas air.
