How To Extract Gold From Sand?
Unlike rock gold mines, gold sand can be directly washed without crushing and grinding. The purpose of the washing operation is to separate the sand from granular soil, and to clean the fine mud adhering to the gravel and mix the gold particles in it. The commonly used washing machine is spiral classifier.

Cyanide Use in Gold Mining
Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.

Cyanide Leaching Of Gold
Carbonaceous gold ores can have the carbon adsorb the gold onto its surface, and as a result will not be recovered from the pregnant solution. Leaching gold from sulfide ores is difficult, at best. Generally, the recovery for cyanide leaching of sulfide or refractory ores is no better than 30%, which is not a worthwhile venture.

Selective attachment processes in ancient gold ore
The report given by Diodorus goes beyond conventional gravity-based gold washing to describe the hand pressing of ore particles on the washing board and the subsequent selective detachment of the sand using sponges (see Fig. 10 left). This procedure is only successful if the gold particles selectively attach to a hydrophobic surface.

Artisanal and Small-Scale Gold Mining Without Mercury | US EPA
Concentration means increasing the amount of gold in ore or sediment, by selectively removing lighter particles. If employed effectively, concentration methods can eliminate or greatly reduce the need for mercury. Before concentration can begin, ore must be crushed or milled to liberate gold particles from rock and to decrease grain size.

Gold Wash Plant for Sale
Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant.The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the wash plant at a steady rate.

» Dry-washing for Gold
Sometimes a road can be bulldozed to your spot. Sometimes you can drive right in with a 2 or 4-wheel drive truck. In these situations, you might consider screening pay-dirt into the back of a truck and hauling it to a wash plant to be processed elsewhere. Actually, this is just slightly more difficult than shoveling directly into a wash plant.
