    Introduction. Figure 1. Aluminum is made from the aluminum-bearing minerals in bauxite. Some minerals are very useful. An ore is a rock that contains minerals with useful elements. Aluminum in bauxite ore (figure 1) is extracted from the ground and refined to be used in aluminum foil and many other products. The cost of creating a product fromAluminum processing Ores Britannica,Aluminum processing Aluminum processing Ores: Aluminum is the third most abundant element on Earth’s surface. Only oxygen and silicon are more common. Earth’s 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.
