Dec 08, 2008· There isn't any gold in pure quartz, but gold often occurs with quartz. Any gold present is usually microscopic. The easiest way to extract the gold is by crushing the quartz and then oxidizing the gold with oxygen in the presence of cyanide ions. The cyanide complexes the gold and allows it to dissolve. This is known as the cyanide process.

To extract the metal from the gold- bearing quartz rock, a determination is made as to the average grain size of the gold. Often these grains are microscopic, and are not discernible by eye.
Gold, being the heaviest element we typically encounter in a stream, can be separated from lighter materials by various gravity separation methods. Gold panning is the most common method used by small scale prospectors, but larger mining equipment like gold dredges, sluice boxes, drywashers, and many other types of equipment uses gravity ...
The main reasons for the partial extraction of gold are "suspicious" gold and "coating" of other minerals on the surface of gold. The shape of the gold particles affects to the choice of method for gold separation. Gravity separation is better to recover gold particles of isometric shape.
