Bauxite is a product of weathering. The name bauxite is derived from its first study area. It has been classified into laterite and terrarossa types. The laterite type bauxite is formed in situ from crystalline rocks and is rich in dibbsite. The terrarossa type bauxite overlies limestone of dolomite and is rich in bochmite. Recommended Videos
