$\: \huge \underline{ \bf{ \red{Answer}}}$

➷In electrolytic refining, the plates of crude metal are anodically dissolved in a suitable electrolyte, while “pure” metal is deposited on the adjacent cathodes.

➷The electrorefining process was introduced about a hundred years ago to produce a substitute to fire-refined copper.

➷Today, practically all of the world’s copper production is electrorefined, constituting by far the largest electrolytic refining industry. Much smaller, but also important, are the electrolytic refining industries producing lead, nickel, silver, and other minor metals.
