摘要
硫脲、氯气是较有可能取代氰化物的提金试剂。本文评述采用这三种浸出剂的提金工艺,结合历史发展和现状,比较方法特征、局限和经济性,讨论和展望它们的应用前景。
Thiourea and chlorine are possible alternatives to cyanide for extraction of gold. An overview of techniques used and general comments of gold recovery using each of the three leaching reagents are given. According to the history and present state of these processes, the characteristics and disadvantages of the methods are compared widely. Their prospects to application are discussed.
