Lateritic Bauxite Deposits – Our Largest Source of Aluminum

The main mineral in the pisolitic bauxite is the aluminium-rich mineral gibbsite or "trihydrate" as it is commonly referred to. Pisolitic bauxite ore is an ideal ore for various reasons. It is located close to the surface so very little cover is needed to be removed to expose it. The bauxite is loose and easily mined with front-end loaders.
