摘　　要：由于目前采用氰化法提金工艺中,使用的浸出剂(氰化物)有剧毒,对生态环境影响巨大,因此,对各种非氰浸金工艺体系的研究成为近几年的重要课题。通过对碘化浸金的理论与应用深入研究发现,采用碘法浸金工艺,具有速度快、效果好、使用的浸出剂无毒、生成的配合物稳定性好等优点,可用来处理含碳质和氧化型难浸金矿,为碘化浸金的工业性应用提供了一定的理论基础。At present,the global gold production process is mainly cyanidation.However,the leaching agent(cyanide)used in cyanidation is highly toxic and has a great impact on the ecological environment.Therefore,the research on various non cyanide gold leaching process systems has become an important topic in recent years.Iodine leaching of gold has many advantages in the leaching process,such as high speed,good effect,non-toxic leaching agent and good stability of the complex.It is used to treat carbonaceous and oxidized refractory gold ores.This paper summarizes the theoretical research and application research of iodized gold leaching,so as to provide a certain theoretical basis for its industrial application.
