Adsorption of gold from cyanide leaching solution onto …
First, the cyanidation (cyanide leaching) experiments were carried out in a tumble bottle under optimal condition of Sarigoni (Qorveh) gold processing plant at ambient temperature, pH of 11, liquid to solid ratio of 2, sodium cyanide concentration of 1 g/L, particle size finer than 74 μm and leaching time of 24 h.For each test, a 300 g representative sample was selected.
Cyanide control in the metallurgical process of gold
The cyanide consumption recorded in the 2019 process optimization test work returned higher cyanide consumptions than anticipated. Upon review by Artemis, the test method used did not allow precise control of pH and in many cases pH values of less than 10.5 were recorded during the course of the leach tests.

Gold Heap Leaching Process
The gold heap leaching process is often used to concentrate gold deposits with small ore bodies or low grades, or both, which cannot be developed and utilized by conventional methods. The main process is to crush low-grade gold ore to a certain particle size (or granulate), stock on a leak-proof bottom pad made of asphalt or plastic and other materials, use low-concentration …
