Minerals Free Full Text Kinetics of Iron Leaching from Leaching of chromium from coal ash using citric acid

Temperature acid concentration and particle size were investigated to determine the most important kinetics parameters during iron leaching It was determined that the rate of iron dissolution increases with increasing of phosphoric acid concentration the temperature and decreased particle size of clay Data obtained showed that iron dissolution from kaolin clay is due to the diffusion of Also the order of the ability of the organic acid to leached chromium are as follows citric acid >gluconic acid >oxalic ac Moreover mixture of 3 organic acids were used with M citric acid M oxalic acid and M gluconic acid with varying contact time Only 862 of chromium was leached after 24 hours using mixed organic ac
