英文摘要The idle mining or flotation decarburization of vanadium-bearing carbonaceous gold ores polluted the environment and wasted resources. In this paper, the volatilization behavior of calcined gold and the extraction kinetics of vanadium from calcined slag were analyzed to increase the high-value utilization efficiency of double refractory gold deposits. The results showed that the high-temperature chlorination efficiency of gold increased with the increase of calcium chloride dosage. At the same time, the oxidation effect of vanadium in roasting slag is also improved, which reduces the cost of extracting vanadium from roasting slag by acid. the vanadium leaching ratio of 83.3% when the calcium chloride amount of 10%, the roasting temperature of 1000celcius, the roasting time of 240min, and the airflow rate of 1L/min, and the gold volatilization rate of 89.9%. The high-temperature chlorination reaction of gold and the acid leaching reaction of vanadium from calcined slag were also controlled by the interfacial chemical reaction. The apparent activation energy of the high-temperature chlorination of gold and the acid leaching of vanadium from calcined slag is calculated to be E = 71.61kJ/mol and 40.82kJ/mol, respectively. Suggested that gold recovery from vanadium-bearing carbonaceous gold ores was achieved using chlorination heat treatment. Also, the possibility of recovering vanadium from the roasting slag was verified by acid leaching experiments.
