Question

Name and describe the most widely used method for refining impure metals?

Answer 1

The most widely used method for refining is electrolytic refining.

In the process, impure metal is employed as the anode, while a strip of purified metal is transformed into the cathode. The electrolyte that corresponds to the solution is extracted. When current is transmitted through an electrolytic cell, impurities dissolve and settle on the anode. Meanwhile, ions generated by metal are deposited at the cathode, resulting in a thicker pure strip and a thinner impure strip.
