摘　　要：硫脲浸金法因具有高效、环保、浸出速度快等优点,是一种很有发展前景的非氰提金法,而生物氧化预处理—硫脲浸金工艺以其条件温和、环境友好、浸金效率高同样倍受关注。详细介绍了硫脲浸金的基本原理、影响因素和浸金液中金的回收方法,以及生物氧化预处理—硫脲浸金联合工艺,并对硫脲浸金的发展进行了展望。Thiourea leaching of gold is one of the most promising alternative gold leaching methods because of its high efficiency,little toxicity and other advantages. Biological oxidation pretreatment with thiourea leaching process has attracted much attention due to its mild conditions,environmental friendliness and high gold leaching efficiency. In this paper,the principle,influencing factors and recovery methods of gold leaching from thiourea are introduced in detail,and the development of gold leaching by thiourea is prospected.
