The two correct answers for why bauxite is the most common ore that aluminum is extracted from are:
1. It is the most abundant ore of aluminum.
2. It is located near the surface and can be easily strip mined.
Bauxite is not pure aluminum, it typically contains aluminum oxide along with other impurities. It also requires a refining process (Bayer process) to extract aluminum, so "it can be refined in a single step" is not correct. Bauxite is not used in jewelry as a gem, as the primary use is for aluminum production.
