摘要:

活性炭作为炭浸法/炭浆法的载金介质,在循环利用中需进行活化再生,以保持其吸附金的活性。从活性炭性质与金吸附原理出发,探讨了载金活性炭活性下降的主要机制。基于此,总结了活性炭活化再生常规技术,介绍了具有大规模应用前景的活化再生新技术,包括新型酸洗柱、超声强化酸洗、强制放电再生、微波再生、电热再生,简述了其作业机理、活化再生效果、技术成熟程度等方面的研究进展,为载金活性炭活化再生技术研究与应用提供借鉴。

Abstract:

As the gold-loaded medium in a CIL/CIP circuit,activated carbon has to be regenerated to keep its activity for Au adsorption.Based on the properties of activated carbon and principles of Au adsorption,the activity decline mechanism for gold-loaded activated carbon is discussed.Based on these,the common techniques for regeneration of activated carbonare are concluded.Several regeneration techniques with industrial prospects are enumerated briefly with their principles,regeneration effects and technical maturity,including new type acid washing column,ultrasonic reinforced acid washing,enforced discharge regeneration,microwave regeneration and electro-heating regeneration.The study provides reference for the research and application of gold-loaded activated carbon regeneration technology.
