| 英文摘要 | To extract the Au efficiently, the kinetic experiments were performed in a 1000 mL-glass bulbs which were made by us to determine the oxidative dissolution of arsenopyrite by iron solution. The results show that the rate of dissolution of arsenopyrite increases with the increasing of temperature from 30 degrees C to 75 degrees C, in which an apparent activation energy for arsenopyrite oxidation is 10.850 kJ.mol(-1). Moreover, the rate of oxidative dissolution of arsenopyrite increases with the increasing of concentration of ferric iron with the reaction order is 0.34 (4.62 similar to 40.04 g.L-1) and 0.61 (27.32 similar to 36.33 g.L-1). In contrast, the reduction of hydrogen ion can promote concentration promotes the leaching rate of arsenopyrite with the reaction order of -0.29. |
