锌置换和炭吸附现在都用于从氰化浸出液中回收贵金属。它们各自有其独特的工艺特点，使之适于处理不同性质的溶液，有着不同的应用。本文对这两种方法进行了评述和比较。得到了北美一些默里尔－克罗威法沉淀和炭吸附厂的操作数据并用于本文的分析。也考虑了两种提金方法的相对投资和操作费用。
Both zinc displacement and carbon adsorption are now used to recover precious metals from cyanide leachate. Each has their own unique process characteristics, making it suitable for handling different types of solutions, have different applications. This article reviews and compares these two approaches. The operating data from some Murray-Cro-Vall method precipitation and charcoal adsorption plants in North America were obtained and used in the analysis herein. Also considered the relative investment and operating costs of the two gold extraction methods.
