On the other hand, with a Merrill-Crowe process, the total capital cost is solely a function of the initial flow rate. Operating costs vary in the CIP plant according to the grade of gold in the leach liquor. This cost does not vary with the Merrill-Crowe except in the case of zinc usage which increases with higher input concentrations.
Merrill–Crowe process explained. The Merrill–Crowe Process is a separation technique for removing gold from the solution obtained by the cyanide leaching of gold ores.
