Drop size distribution in a mixer-settler reactor for the gold chloride/DBC system

► The dependency of the drop size distributions on impeller speed, and phase fraction were studied for gold chloride-DBC system. ► The Sauter mean diameter, D32, has been correlated for both systems in the frame of the classical Hinze-Kolmogorov theory. ► The prediction of mean drop size diameter in the leach solution is possible by using synthetic solution data with AARD <10%.
