It is not based on 'solubility'. Rather, it is based on the principle of differential wettability of the ore and gangue particles. Electromagnetic separation works when either ore or gangue are magnetic (attracted to magnets) in nature. Crushing and grinding happen before concentration. It is not a concentration process at all.
