Aluminum Processing Ores Britannica

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.
