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.

Gravity separation is most effective on gold ores with large differences in density between gold and other minerals. Some examples include the placer gold deposits where the gold is free and easily amenable to separation from the other minerals and the lode gold deposits that contain large and coarse gold particles.

Gravity is fundamental in gold - ore separation because gold has a relatively high density compared to most of the gangue (waste) minerals in the ore. When the ore is processed in a gravity - based system, the force of gravity causes the denser gold particles to move in a different way than the less - dense waste materials.
