Aluminum processing - Aluminum processing - Ores Aluminum is the third most abundant element on Earths surface. Only oxygen and silicon are more common. Earths crust to a depth of 16 km 10 miles contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.
Bauxite mining in the United States - Wikipedia. Bauxite forms by the weathering of aluminum-rich and silica-poor rocks in hot, humid, climates, at places with good drainage. Under the proper conditions, weathering disintegrates the aluminium silicate minerals, and dissolves and removes the silica, creating bauxite.
