Question

What are the various steps involved in metallurgy?

Answer 1

Metallurgy is the science and technology of metals. It deals with the production of metals, their purification, and alloying.

The various steps involved in metallurgy are:

1. Crushing and grinding: The ore is crushed into a fine powder in big crushers and ball mills.
2. The concentration of ore: Removal of unwanted impurities such as rocks, and sand from the ore is called concentration of metal in mineral ore by removal of gange.
3. Roasting and calcination: The process of conversion of concentrated ore into metal oxide by roasting or calcination.
4. Reduction: The metal oxides are reduced to the corresponding metals by using a suitable reducing agent.
5. Refining: The purification of impure metals by removing metallic and non-metallic impurities is called refining.
