If gold particles are not adequately liberated from the ore, they will remain attached to the gangue, thereby reducing the efficiency of the gravity separation process. In simpler terms, the higher specific gravity of gold compared to other minerals means that, once liberated, gold can be more effectively separated using gravity-based methods.
