Here is how it works, without the needless complication of the potentiometer. First, start with a standard Daniell cell with standard assumptions, i.e., negligible internal resistance, unimolar ...

You see, in electrolytic refining, the goal is to get pure metal on the anode. Let us take a specific case of electrolytic refining of $\ce{Cu}$. Normally we would use $\ce{CuSO4}$ solution, so let us take that case. Impure copper is set as the anode, $\ce{Cu^{2+}}$ ions are released. But you see, the $\ce{Cu^{2+}}$ ions from the anode don't directly go to ...
