In the mining industry, electrolysis has been used for the extraction of certain metals. For example, copper can be purified through electrolytic refining. This process helps in obtaining high - purity copper which is essential for electrical applications. The success of this method has made it a standard in the copper production industry, ensuring the quality of copper used in wiring and electronics.
Sure. In the aerospace industry, electrolysis is used for surface treatment of certain components. It can create a protective oxide layer on metals like aluminum, which enhances the durability of parts in the harsh aerospace environment. This has contributed to the safety and longevity of aircraft.
