Answer :

Zirconium and Hafnium do belong to the same group but that is not the reason why separating them is difficult. Lanthanide contraction due to poor f orbital shielding leads to an increase in effective nuclear charge, which reduces the size of Hf. So the atomic radii of both Zr and Hf are similar which means they have similar physical and chemical properties and hence separation becomes difficult.
