Answer
The primary ore of aluminum is bauxite. Bauxite is formed through the weathering and leaching of aluminum-rich rocks, such as feldspars and micas, in tropical or subtropical climates. Over time, the rainwater and weathering agents break down the aluminum-bearing minerals, and the aluminum is carried by water and concentrated in low-lying areas or as residual deposits. These accumulations of concentrated aluminum minerals are the bauxite ore deposits.
