This is a much less abrasive system meaning that the carbon lasts much longer than in a CIP process. Carbon-in-columns During this process, the cyanide leaching solution passes through columns filled with ore. The process is highly effective for removing gold from low grade ore.

2022-5-13 Gold cyanidation process refers to the method of extracting gold with cyanide as leaching solution. Since it was used in mines to extract gold and silver in 1887, it has a history of more than 200 years, and the technology is relatively mature. Cyanidation is still one of the main methods of gold production due to its high recovery rate, strong

2020-12-4 The Cyanidation process contributes to the recovery of more gold. The process is about oxidation and dissolving of metallic gold in an alkaline cyanide solution. Atmospheric oxygen acts as the oxidant in the process. The oxidant helps to dissolve the gold and forms sodium hydroxide as well as sodium cyanoaurite.
