Gold Separation From River Sand

In the current situation where the price of gold is at a 20 year high and in an attempt to meet this foreseeable demand for gold, the prospect of recovering gold and heavy minerals of economic interest from sand and gravel normally used for aggregates is assessed. To date, these minerals, with rare exceptions, have been ‘lost’ in the manufacture of concrete for public works and construction. The authors propose a methodology for the recovery of these minerals in the most cost effective way possible.

gold mining and panning

Gold mining is the removal of gold from the ground. There are several techniques and processes by which gold may be extracted from the earth. Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As gold is much denser than rock, it quickly settles to the bottom of the pan. The panning material is usually removed from stream beds, often at the inside turn in the stream, or from the bedrock shelf of the stream, where the density of gold allows it to concentrate, a type called placer deposits.

Sand and gravel plants together with crushed stone quarries produce materials known as aggregates. According to the European standard, aggregates, which may be natural, artificial or recycled, are granular materials used in construction worldwide.
