Wt is electrolytic refining
Answers
Explanation:
Electrolysis, or electrolytic refining, is a technique used for extraction, as well as purification, of metals obtained by any refining method. In the electro-refining process, a block of impure metal becomes the anode, and a thin sheet of metal becomes the cathode. Both the cathode and anode are dipped in an electrolytic cell containing an aqueous solution of the metal salt. Upon the application of electric current of a suitable voltage, pure metal is deposited at the cathode by the dissolution of impure metal at the anode.
ELECTROLYTIC REFINING IS THE PROCESS OF REFINING A METAL BY THE ELECTROLYSIS OF A SOLUTION OF THE SALT OF THE METAL ,USING A SMALL PIECE OF PURE METAL AS THE NEGATIVE ELECTRODE AND THE IMPURE METAL AS THE POSITIVE ELECTRODE.COPPER CAN BE REFINED THROUGH THIS METHOD.
