What is a method of extracting metals? One way of extracting metals from its ore can be electrolysis. What is electrolysis and how does it work?
Name: Copper
Symbol: Cu
Atomic Number: 29
Element Category: Transition Metal
Substance: Solid
Extracted From: Sulfate Ore and Chalcopyrite
Electrolytic refining is a process of getting pure metal by
the process of electrolysis. In the procedure an electric current is passed
through a solution called electrolyte that contain dissolved metals. This cause
the dissolved metal to stay on the negatively charged cathode. Take a copper ore or impure copper which is the anode and
pure copper as cathode, with there put it in a cell containing acidified
solution of copper sulphate as electrolyte. When you send an electric current
through the electrolyte, you can see that the copper from the impure copper
anode dissolves in the solution as CU 2 plus ions. These ions changes to copper
when it reaches the cathode and deposits on it.
