Title
Oxidation Kinetics of Liquid Lead
유재근Jae Keun Yoo, 김학영Hak Young Kim, 백영현Young Hyun Paik
Abstract
Effects of temperature, oxygen partial pressure and the addition of impurities, such as Sb and in on the oxidation rare of liquid lead were investigated to provide fundamental data in the dressing stage of pyrometallurgical refinning of lead. In this study temperature and oxygen partial pressure were in the range of 700 to 850℃ and 0.2 to 0.8 atm, respectively. The results showed that the oxidation rate of liquid head was found to follow the parabolic rate law, and that the oxidation rate was increased with increasing temperature, oxygen partial pressure, and also impurity content. The activation energy was for found to be about 39 ㎉/mole for the oxidation of liquid lead.
