Dense medium processing for coal Gravity Separation Concentration
The dense media specific gravity is based on the amount of medium that is suspended in the water. So the answer to your question is obviously which is when you have no media added. In effect this is how a jig works. But in actual fact the density of the media will never reach due to circulating fines and other factors.
