The process of removing impurities from metals is called refining. Refining is crucial in metallurgy, where raw ore contains various unwanted elements mixed with the desired metal. Different techniques, such as smelting, electrolysis, and chemical baths, can be employed depending on the metal and its impurities. For example, electrolytic refining uses electric current to separate pure metal from its ore. The end goal of refining is to produce high-purity metals that meet industry standards for various applications, including electronics, construction, and manufacturing, ultimately enhancing the overall quality and value of the metal.
