The goal of the present research is to study the impact of a stationary wiper almost touching a revolvingzinc solid cylinder on the rate of Cu+2 cementation. Initial Cu+2 ions concentration, speed of rotation, andthe effect of the presence and absence of a wiper were investigated. The degree of Cu+2 cementation wasstated in relation to the mass transfer coefficient which was valued under diverse circumstances. Thepresent study showed that the mass transfer coefficient accelerates as rotation speed and quantity of Cu+2increase. The presence of a wiper enhances the degree of Cu+2 cementation by an extent that varies from1.59 to 64% subject to the operational circumstances. The present mass transfer data have beeninterrelated by dimensionless equations. The importance of such relationships in the sizing and runningof rotating cylinders used for performing diffusion- restricted reactions is underlined.
