Separating emulsions
Gravity Separation. Gravity separation is the most common method used in the oil industries. It depends on the differences in the densities of oil and water in the emulsion. Density differences allows water to settle down due to the water having a higher density than oil. Being in a non turbulent state, the specific gravity between them helps ...
Chapter 4 Gravity Concentration
The specific gravity of gold is 19.5 and the specific gravity of quartz (the common gangue mineral associated with gold) is 2.65 (i.e., gravity concentration works because gold is heavy, and quartz is light).
