dc.description.abstractIn this work, dissolution of Ni and Fe in sulfuric acid medium under the influence of sodium fluoride was studied. The samples of the nickeliferous lateritic ore were taken from Eskisehir (Karacam) region of Turkey. The effects on the nickel and iron dissolution rates of stirring speed, sulfuric acid concentration, sodium fluoride concentration, reaction temperature were investigated. In order to investigate the effects of leaching temperature range of 30-50 degrees C the shrinking core model was applied by using the results of experiments. Kinetics analysis showed that the nickel and iron dissolution from lateritic ore could be described by the "diffusion" for nickel and "surface chemical reaction" for iron, respectively. The activation energies (Ea) and Arrhenius constants for the dissolution reactions were calculated.en_US
