The provided context explicitly outlines the 'Process of Manufacturing in Aluminium Industry', identifying Bauxite as the raw material. The flowchart indicates that bauxite is crushed to produce alumina, which is then processed in an Aluminium Smelter. In contrast, the context notes that the Iron and Steel Industry uses iron-ore, coking coal, and limestone, and the Chemical industry section mentions soda ash for paper, but neither mentions bauxite as a raw material.
