Oxygen Sparging Improves Gold Leaching - EFD Home Page

Generally, leach tank agitators are designed to keep the pulp in motion, i.e. down the centre, out to the wall an up the tank sides. In some leach tanks air blowers introduce air flow below the agitator blades which can cause an erratic slurry flow and inefficient mixing . In an effort to improve mixing the air flow is typically increased.
