| 英文摘要 | To realize the efficient comprehensive utilization of refractory gold ore resources and environmental and economic gold extraction methods, this study investigated the optimal chlorine source for the sustained recovery of gold and vanadium from carbonaceous refractory gold ore by chlorination heat treatment. During the chlorination roasting process, the results indicated that CaCl2 has a greater chlorine supply capacity, and the reaction of refractory carbonaceous gold ore with CaCl2 was more intense than other chlorine sources. In addition, the effect of significant parameters (such as heat treatment temperature, heat treatment time, and CaCl2 additions) on gold and vanadium recovery ratios was carefully investigated. Under ideal conditions (i.e., CaCl2 concentration of 10 pct, heat treatment temperature of 1100 degrees C, heat treatment time of 4 hours, and air velocity of 1 L/min), 89.91 and 83.26 pct of gold and vanadium were recovered, respectively. In comparison, the main chemical mechanisms and phase transitions during the roasting process were studied by some analytical methods (such as scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, and thermodynamic data). All alkaline chlorine sources were shown to destroy the structure of the minerals. CaCl2 was the compound with the more potent effect. Pyrite could enhance the chlorination of gold below 700 degrees C. In contrast, vanadium oxide could promote chlorination of gold above 700 degrees C. In addition, the leaching residue is primarily made of CaVO3, which can be used as a raw material for vanadium smelting. However, silicon dioxide and iron oxide will react at temperatures above 1100 degrees C, forming the "silicon oxygen" inclusion that hampered vanadium extraction. |
