Introduction to Aluminium Industry

1. Introduction To Aluminium Industry

2. Introduction to Bauxite Ore Is an aluminium Ore. Is the main source of aluminium. It is not a mineral rather it is rock that has been several leached of silica and other soluble minerals. It Is found majority (90%) in wet tropical and subtropical climate.

3. What is Alumina (Al 2 O 3 )? Alumina is the final product of Bayer’s process. (It’s a Chemical process turns bauxite into alumina) White crystalline substance. Used as the starting material for the production of aluminium metal.

4. Alumina to Aluminium (Primary) To produce pure aluminium, alumina is smelted using the hall- heroult electrolytic process. Primary aluminium include: Ingot, Billet, Slab, Sow, Wire rod.

5. Aluminium Ingot Aluminium Billet Aluminium Slabs Aluminium Wirerod Casted Components, Extrusions, Rolled Coils (Remelted Products) Extrusions (Profiles, facades, etc), Bars & Rods, Tubes & Pipes FRP (Plates, Sheet, Strips), Foil Wires & Cables Semi-Fabricated Products Primary Aluminium

7. Pre-consumer scrap : Scrap arising from the production of aluminium and its alloys, and from the fabrication of semi-fabricated (mill) products and end-products. It is scrap that arises during the manufacturing process. Pre-consumer scrap returns directly to recycling plants for remelting. Post-consumer scrap : Scrap arising from the disposal of products after they have been used. This type of aluminium scrap must be collected and sorted before it can be remelted at recycling plants. Difference in Recycled Aluminium
