摘　　要：碘化浸金是一种新的非氰化浸金方法。文章详细介绍了不适合浮选处理的含碳原生金矿焙烧试验和碘化浸出时各影响因素试验。分析了各种实验现象 ,通过试验得出了合理的焙烧温度为 6 5 0℃、碘化浸出率可提高 15 %左右 ,浸出速度快等结论。Leaching of gold is a nwe method for non-cyanidation leaching gold.Experiments of roasting the carbonaceous primary gold ore that connot be treated with flotation and the affecting factors of iodide leaching glod are intrduced in this paper.In the Experiments,many experimental phenomenon have been analyzed and the results are gotten out that the logical temperature of roasting ore is 650℃,the leaching rate of gold can be increased 15 percent and the leaching velocity is higher than other methods.
