Extraction Of Iron Process

Iron | Sajha Notes

This is the modern process for the manufacture of steel. For the manufacture of steel, 70-80% cast iron, 20-30% scrap iron and a little haematite is used. The charge is heated by passing producer gas (CO + N 2 in 1:2) and the process works on a regenerative system of heat economy. Oxidation is carried by haematite.

Extraction of Zinc: Process, Ores, Diagram

The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.
