dc.description.abstractIn this study, leaching of Ni and Fe in suphuric acid medium with K2Cr2O7 was investigated. The samples of the lateritic nickel ore were taken from Karacam (Eskisehir) region of Turkey. Mineralogical investigations showed that the ore sample contains, goethite, hematite, wustite, retgersite, gaspeite and clay type minerals together with quartz. The shrinking core model was applied to the results of experiments investigating the effects of leaching temperature range of 50-96 degrees C. Two equations were applied from obtained results from each temperature value. Their correlation coefficients for each temperature are calculated. These results indicate that the dissolution rate of Ni is controlled by diffusion. The activation energy for the leaching process was found to be 68.43 kJ/mol and the Arrhenius constant was calculated to be 8.231 s(-1).en_US
