Gravity Separation & Concentration Methods
In placer gold mines, gold usually exists in the form of single natural gold, and its density is generally greater than 16 tons/m3, which has a large difference with the density of gangue. Therefore, gravity separation is the most important, most effective and most economical way to select placer gold mines. Methods.
