One of the approaches taken to isolate the gold from the soil was called “panning.” Dirt would be placed in the pan and covered with water. After thorough mixing, the pan is gently swirled to remove dissolved material while the heavier gold settles to the bottom of the pan. The gold is then separated from the mixture of soil and water.

Fine Gold Recovery. Separating Placer Gold Particles

Separating fine gold particles from black sands is one of the biggest challenges that gold prospectors have to deal with. This article will describe a simple and inexpensive method of capturing fine gold. Most small scale prospectors do not need to invest thousands of dollars to capture small placer gold dust. Using fine gold recovery methods, you can retain the vast majority of gold

ore. Relatively coarse gold particles that are liberated from the gangue mineral phase by crushing and grinding are readily recovered by gravity techniques, because of the large difference in specific gravity between gold (SG 19.3) and most gangue minerals (SG 2 to 3). For gold ores that are amenable to gravity separation, recovery of the coarse,

Separation Techniques. A separation process or technique is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures. At least one of results of the separation is enriched in one or more of the source mixture’s constituents. In some cases, a separation may fully divide the mixture into
