Aluminium mining is the extraction of the ore of Aluminium bauxite To mine bauxite you would need to use oil another fossil fuel powered machines and dynamite So the answer is NO coal Bauxite is acquired through environmentally responsible strip mining operations Because the bauxite is located close to the surface mining disrupts only the surface There is no need to dig deep trenches or even blast rocks into the orbit for extracting the ore

Bauxite is the principal ore of aluminum The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process In the Bayer Process the bauxite is washed in a hot solution of sodium hydroxide which leaches aluminum from the bauxiteAlumina Extraction Problem In the standard Bayer Process for refining bauxite to produce alumina the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch
