Özet
Dissolution kinetics of nickel from lateritic ore in nitric acid solution was investigated. Experimental parameters used were stirring speed (100-600 r/min), temperature (40-96 A degrees C), nitric acid concentration (0.1-2 mol/L) and particle size (< 106 A mu m). The shrinking core model was applied to the results of experiments investigating the effects of leaching temperature in the range of 40-90 A degrees C and nitric acid concentration in range of 0.1-2 mol/L on nickel dissolution rate. The kinetic analysis shows that the nickel dissolution from lateritic ore could be described by diffusion model. The activation energy (E (a)) for the dissolution reaction is calculated as 79.52 kJ/mol.
