对山东某焙烧氰化渣进行了氯化挥发提金的研究，将原料配入CaCl₂造球、烘干，将球团在不同条件下焙烧，分析焙烧前后的元素含量变化。结果表明：氰化渣中配入4%的CaCl₂造球烘干，在1 050 ℃下焙烧，金挥发率能达到85.93%，且在该温度下未发生熔融，证明使用氯化挥发法提取焙烧氰化渣中的金是可行的。实验中还发现，CaCl₂的分解温度远低于适宜的挥发温度，因此升温时间、中温停留时间过长会导致CaCl₂提前分解，影响金的挥发。

The recovery of gold from residue of roasting-cyaniding process in Shandong Province by chloridizing roast is investigated.Raw material with CaCl₂ was pelletized，and then dried.Dried pellets were roasted in different conditions.Composition change was analyzed.The experimental results demonstrate that the volatile ratio of gold reaches 85.93% when tailing pellets with 4% CaCl₂ added roasted at 1050 ℃ for one hour，and the pellets are not fused at that temperature.It proves that gold recovery from residue of roasting-cyaniding process by chloridizing roast is workable.The experiments also shows that the decomposition temperature of CaCl₂ is far below volatilization temperature，and too long heating up time or dwell time at middle temperature may cause decomposition ahead of schedule，thus influencing the volatilization of gold.
