The kinetics of the cementation of chromium ions from potassium dichromate solution onto fluidized bed of iron particles were investigated in a stirred tank reactor. Variables studied were physical properties of the solution, stirring speed (rpm) and temperature. The rate of cementation was found to increase with increasing rpm and concentration. The rate of cementation was expressed in terms of the liquid–solid mass transfer coefficient (k). The data were correlated by the equation:

Sh=0.52 Sc0.33Re0.4957

The high rates of mass transfer obtained in this work and the high area per unit volume of fluidized bed of iron qualify them for building high space time reactors suitable for purification of hydrometallurgical leach liquors and removal of heavy metal from waste water by cementation.
