Metallurgy is a branch of materials science and engineering that focus on the studies of the physical and chemical behavior of metallic elements.
A process used to extract metals in their pure form is referred to as metallurgy.

Chemical methods
Calcination
– It is a chemical separation method for carbonate or hydrated oxide ores.
Roasting
– Calcination is similar to roasting, but this process is concerned with the changes caused by the expulsion of some ingredients such as water and carbon dioxide.– It is a chemical separation method for carbonate or hydrated oxide ores.
Reduction (Extraction of metals)
Smelting– It is a process that involves melting in which a metal is separated from its ore.
Carbon-reduction process (Smelting
Reduction by Aluminum (Aluminothermic or Gold-Schmidt alumino thermic process)
