Answer 1

Answer:

The red coloured mineral of aluminium is Bauxite .

Explanation:

What is Bauxite?

Bauxite is the primary ore of aluminum. Almost all of the aluminum that has ever been produced has been extracted from bauxite. The united States has a few small bauxite deposits but at least 99% of the bauxite used in the United States is imported. The United States is also a major importer of aluminum metal.

Many people are surprised to learn that bauxite is not a mineral. It is a rock composed mainly of aluminum-bearing minerals. It forms when laterite soils are severely leached of silica and other soluble materials in a wet tropical or subtropical climate.
