  • cyanidation process for gravity separating new

    The gold cyanidation process is a primary method of gold beneficiation. 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.
