  • Activated Carbon in Gold Cyanidation

    Activated Carbon in Gold Cyanidation

    Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation. Here too, activated carbon is the catalyst for recovery of this precious metal

    1. Carbon-In-Column (CIC): With carbon-in-column operation, solution flows through a series of fluidized bed columns in an upflow direction. Columns are most frequently open topped, but closed top pressurized columns are occasionally used. Carbon columns are most commonly used to recover gold and silver from heap leach solutions

    Why Put a 'V' in your CIC? - Morrison-Maierle

    May 14, 2020 The pregnant solution flows through the carbon columns, which are generally situated in a step-down arrangement so that the overflow from the highest elevation column will flow to the next column. The gold absorbs onto the surface of the carbon. The loaded carbon is periodically removed from the columns and sent for stripping
