Adsorption of gold from cyanide leaching solution onto activated carbon

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 Bottle Roll Leach Test – Leaching Procedures

Be sure to use at least 500g, but 1000g per test is better. Be sure to use a big enough bottle. You need to lay it on its side to use it on the roller while having a small hole in the lid to allow air inside. Alternatively you can use an air bubbler during the leach.
