Gold is mainly extracted from its ores or concentrates by leaching with oxygenated cyanide solutions .Cyanide consumption during leaching, and the discharge of excess cyanide in wastewater, respectively constitute major economic and environmental costs in the gold industry.Cyanide losses in the leaching stage mainly occur via the action of cyanicides: minerals, such as the
A cyanide bottle roll test is the industry standard first step in assessing the gold recovery possible by cyanide leaching. During a bottle roll test, prepared ore is gently agitated in a cyanide lixiviant or leaching solution. Oxygen levels, alkalinity, acid consumption and other parameters are monitored and strictly controlled throughout the test. Test results provide information on expected
The cyanide solution percolates through the ore and dissolves the gold, which is then removed from the lixiviant by adsorption onto carbon or resins. Grain size, oxygen and alkalinity levels are carefully controlled to ensure maximum gold recovery. Heap Leaching. Heap leaching facilitates the profitable extraction of gold from very low grade

Potassium gold cyanide is known to be highly toxic to humans as well as the environment, particularly to aquatic life. Mishandling it or the gold bath may lead to release of cyanide gas. Unfortunately, there are few cyanide free immersion gold bath chemistries available that demonstrate the bath stability, control and high repeatability performance as those containing potassium gold cyanide.
resulting goldplex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the goldplex onto carbon is reversed. Loaded carbon is removed from the CIL circuit and the gold stripped from the carbon using a number of treatment steps. The result is a solution of high
01/06/2020· First, the cyanide extraction rate of gold is limited dramatically at low temperatures <10 °C, and much extra energy is consumed for heating the leaching tank in winter.
