The gold processing plant at the Agnew Mine is capable of handling 1.3 million tonnes of ore a year. It uses the conventional technique of crushing and grinding before feeding the ore into a gravity and CIP circuit. A Knelson concentrator provides the gravity circuit along with an in-line leach reactor.

The dilution-gravity method (DGM) was acquired by water floatation to improve high dense metals concentrations in less amount of WPCBs’ powders, based on the specific gravity. Gold, palladium, silver, copper, lead, tin, and iron with high specific gravity can be separated from those with low specific gravity.

Flotation is also widely used in gold recovery from gold-containing ores and it’s regarded as the most cost-effective method for concentrating gold other than gravity concentration technique. Stephen (2003) has found out that large gold flakes required at least four times the collector loadings of smaller gold grains in order to float.

Gold Gravity Concentration. The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require

How to extract gold from sand? Differ from rock gold separation method, it is relatively simple to extract gold from sand. There are many simple methods, like panning, using a rocker box, using a sluice box, amalgamation and etc.. But it is proved that gravity separation method is the most effective and economic method through lots of practice.

Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from low-grade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the gold-containing solution is leached. Then used the method of carbon adsorption, zinc powder displacement
