Statistical Treatment of Bleaching Kaolin by Iron Removal 263 Effect of temperature Fig. 4 shows that iron removal increases with temperature and is greater at the temperature of 100 °C. This result is attrib-uted to the fact that the non-reductive dissolution pathway is a simple desorption process. It involves desorption of the
Statistical analysis was conducted to determine the most influential factors in the dissolution of iron from the kaolin mineral. Our goal was ferric iron solubilization and its reduction to ferrous iron to improve the iron removal in the acid medium. Leaching experiments were conducted at atmospheric pressure.
