General Principles and processes of Isolation of Elements
easy
In electrorefining of copper, some gold is produced as
A
Cathode mud
B
Anode mud
C
Cathode deposite
D
Anode deposite
Solution
In Electrolytic refining, the impure metal is made to act as an anode. A strip of the same metal in pure form is used as the cathode.
They are put in a suitable electrolytic bath containing a soluble salt of the same metal.
The more basic metal remains in the solution and the less basic ones go to the anode mud.
Copper is refined using an electrolytic method.
Impurities from the blister copper deposit as anode mud which contains antimony, selenium, tellurium, silver, gold, and platinum; recovery of these elements may meet the cost of refining.
