中文摘要: 以焙砂为原料，对熔盐挥发的氯化挥发时间、熔融时间、氧气供应量、氯化添加剂量和氯化剂添加方式进行试验研究。结果表明，在分批加入8%氯化钙、氧气通入量为3 m3/h、融化电压约410 V、融化电流约40 A、熔融温度1 200 ℃、熔融后保持电流约20 A的条件下，金的挥发率稳定在97%以上。并提出一种短流程无氰提金新工艺。
Abstract:A test of molten salt chlorination was performed on gold-bearing calcine and effects of volatilization time, melting time, oxygen supply rate, chloride addition and adding mode on gold volatilization rate were investigated. The results show that gold volatilization rate is 97% above under the optimum conditions including CaCl2 addition of 8%, oxygen flowrate of 3 m3/h, melting voltage of ~410 V, melting current of ~40 A, melting temperature of 1 200 ℃, and holding current after melting of ~20 A. A new short route cyanide-free gold extraction process is proposed.
