Unit Starter: Analyzing Patterns in Resource Distribution Bauxite (BAWK•syt) ore, which is rich in aluminum oxide, is the world’s primary source of aluminum. Bauxite forms deep in the soil when warm rainwater soaks into the ground and removes some minerals and chemicals from the soil. This leaves behind concentrated aluminum.
