Solution
- Metallurgy is a process of extracting metals from their ores by doing various operations such as crushing, concentration, chemical treatment, refining etc.
- The extraction of a metal from its ore involves the following steps:
- Concentration of the ore: This process involves the removal of the undesired impurities i.e., gangue, from the ore.
- Conversion of concentrated ore to oxide: This process is usually carried out by calcination or roasting.
- Reduction of metal oxide to metal: This process is carried out by using reducing agents.
- Refining of metal: The metal is refined usually by the process of electrolysis.
