摘　　要：氯化提金是一种重要的无氰提金工艺方法,因为其具有浸出率高、且不使用氰化物的优势而越来越被重视。2010年以来氯化提金研究呈现明显增加趋势,且液氯化提金研究文献更多。氯化法提金工艺诞生不久,氰化法相继问世,当时由于材料工业比较落后,氯化法面临的腐蚀问题限制了其发展,随之被氰化法所替代。2000年以来,材料科学得到了迅猛发展,先进的耐腐蚀材料为氯化法扫清了障碍,随着人类社会的发展,工业生产所带来的生态平衡和环境保护问题超过了工业发展的本身,因此,氯化提金工艺将会得到更大的发展。Gold extraction by chloride is an important cyanide-free gold extraction process,which has been paid more and more attention because of its advantages of high leaching rate and no use of cyanide.Research on gold extraction by chlorination has shown a significant increase since 2010,and there are more literatures on gold extraction by liquid chlorination.Soon after the birth of the chlorination gold extraction process,the cyanidation method came out one after another.At that time,due to the relatively backward material industry,the corrosion problem faced by the chlorination method restricted its development,and was subsequently replaced by the cyanide method.Since 2000,material science has developed rapidly,and advanced corrosion-resistant materials have cleared the way for the chlorination process.,moreover,with the development of human society,the ecological balance and environmental protection issues brought about by industrial production surpass the industrial development itself Therefore,chlorinated gold extraction process will be further developed.
