Refining of Crude Metal

Metallurgy could be defined as a technique by which metals can be extracted in their pure nature. Extractive metallurgy directs with the route of eradicating the valuable metals from ores and purifying the extracted metals to pure nature. In hydrometallurgy, the metal extraction’s from their ores is done using an aqueous solution. In the pyrometallurgical process, high temperatures are employed to initiate the reactions between gases, molten metals, and solids. In electrometallurgy, the technique is carried in an electrolytic cell.
