What is difference between electrodeposition and electrorefining
Answers
Answer:
Electrorefining is a process in which metals such as gold, silver, and copper are purified or refined, ie other substances are separated from them. Electroplating is the process in which one metal is coated over another by the process of electrolysis.
electrodeposition: Electrodeposition is a well-known method to produce in situ metallic coatings by the action of an electric current on a conductive material immersed in a solution containing a salt of the metal to be deposited.
Electrorefining: Electrorefining refers to the process of using electrolysis to increase the purity of a metal extracted from its ore (compound or mixture of compounds from which a metal can be extracted commercially). ... Electrorefining can be used to purify a number of metals including copper, nickel, cobalt, lead and tin.
