## Main Types Of Metallurgical Processes

Category : JEE Main & Advanced

Different metallurgical processes can be broadly divided into three main types

(1) Pyrometallurgy : Extraction is done using heat energy. The metals like $Cu,\,Fe,\text{ }Zn,\,Pb,\,Sn,\,Ni,\,Cr,\,Hg$ etc. Which are found in the nature in the form of oxides, carbonates, sulphides are extracted by this process.

(2) Hydrometallurgy : Extraction of metals involving aqueous solution is known as hydrometallurgy. Silver, gold etc are extracted by this process.

(3) Electrometallurgy : Extraction of highly reactive metals such as $Na,\,K,\,Ca,\,Mg,\,Al$ etc. by carrying electrolysis of one of  the suitable compound in fused or molten state.
