General Principles and processes of Isolation of Elements
easy
Poling process is used for
A
The removal of $Cu_2O$ from $Cu$
B
The removal of $Al_2O_3$ from $Al$
C
The removal of $Fe_2O_3$ from $Fe$
D
All of these
Solution
Poling is a method employed in the purification of copper which contains cuprous oxide as an impurity.
The impure metal, usually in the form of molten blister copper, is placed in an anode furnace for two stages of refining.
