Copper Mining & Extraction Process Flow Chart

Although aluminum is the most reactive metal in common use, it is highly resistance to weathering and corrosion. When exposed to air, aluminum quickly forms an invisible oxide layer on its surface that protects the metal from further corrosion. This oxide layer is thickened in a process termed ?anodizing.? Anodized aluminum is commonly used to coat cookware.
