We are fortunate that the Moon has concentrations of aluminum in an attractive mineral form, anorthite. As McKay and Williams conservatively report: "Anorthite can be considered to be a potential aluminum ore in the sense that it is a naturally occurring concentration of aluminum from which it may be economically feasible to extract the metal.

The History of Aluminum and Charles Martin Hall
Aluminum is the most abundant metal element in the earth's crust, but it is always found in a compound rather than an easily-refined ore. Alum is one such compound. Scientists tried to tease the metal out of alum, but the process was costly until Charles Martin Hall patented an inexpensive method to produce aluminum in 1889.

The strong affinity towards oxygen leads to aluminium's common association with oxygen in nature in the form of oxides; for this reason, aluminium is found on Earth primarily in rocks in the crust, where it is the third most abundant element after oxygen and silicon, rather than in the mantle, and virtually never as the free metal.
