    VALVES FOR GOLD LEACHING IN CIL, CIP OR CIC CIRCUITS

    The most widely used processing method in gold production is cyanidation for carbon-in-leach (CIL), carbon-in- pulp (CIP) or carbon-in-column (CIC) circuits. The gold leaching process starts with comminution. The run-of-mine ore is crushed and ground to a fine particle size. Water is added to the process to create a mud-like slurry.
