Abstract Mechanically agitated vessels are used widely in mineral processing industry for carrying out solid-liquid operations such as adsorption, leaching, ion-exchange and other chemical processes. Many of these solid-liquid agitated systems are required to process slurry with high solids concentration for the purpose of process intensification. Process intensification in agitated vessels requires that the production rate per unit volume has to be increased without major changes in the geometry ofthe existing infrastmcture. Recently, Wang et. a!. (2011) have suggested that operating a solid-liquid mixing vessel at a relatively higher solids concentration of~ 0.20 (v/v) is preferable due to a higher energy efficiency at this condition and the possibility of suspending more solids for every unit of power input. However, to date, not much attention has been paid to study the effect of high solids concentration on solidliquid mass transfer. Most of the previous studies on solid-liquid mass transfer involve relatively low solids concentration(< 0.10 v/v). Therefore, this study aims to investigate the influence of high solids concentration on solid-liquid mass transfer coefficient.
