Question

define electrolyte refining

Answer 1

Refining of a metal (such as copper) by electrolysis, the crude metal used as the anode going into solution and the pure metal being deposited upon the cathode.

Answer 2

Many metals such as copper , zinc , tin , etc,.are refined electrolytically. In this process the impure metal is made 5he anode and a thin strip of pure metal is made the cathode. A solution of the metal salt is used as an electrolyte. On passing the current through the electrolyte,the pure metal from the anode dissolves into the electrolyte. An equivalent amount of pure metal from the electrolyte is deposited on the cathode The soluble impurities go into the solution ,whereas,the insoluble impurities settle down at the bottom of the anode and are known as anode mud.
