Eight Agitators in each series are operational, with the ninth employed as a stand-by. Each series of eight agitators handles 19,800 gallons per minute of slurry, and the reaction time is three hours. Results at this plant are excellent, enabling this plant to realize a high alumina extraction with a minimum.
