    Aug 15, 2006Aluminium casting processes are classified as ingot casting or mould casting. During the first process, primary or aluminium is cast into rolling ingot (slab), extrusion ingot (billet) and wire bar ingot which are subsequently transformed in semi- and finished products. The second process is used in the foundries for producing cast products.

  • How do we extract minerals?

    Sphalerite, zinc sulfide, is and has been the principal ore mineral in the world. Zinc uses range from metal products to rubber and medicines. Zinc alloys readily with other metals and is chemically active. On exposure to air, it develops a thin gray oxide film (patina), which inhibits deeper oxidation (corrosion) of the metal.
