Aluminum is the most abundant metal element in the Earth's crust. Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral.

So, to obtain a tonne of the element, roughly 200 tonnes of ore must be extracted, apart from any waste rock and overburden. For many of the critical minerals needed in clean energy technologies, ore grades are much lower. For cobalt, for example, roughly 1500 tonnes of ore must be mined and processed for each tonne of element recovered.

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. Its compounds, however, are an important constituent of virtually all common rocks.
