摘要：
A method for treating a silver-containing zinc alloy, the method comprising treating the alloy in a process vessel under conditions of elevated temperature and sub-atmospheric pressure so as to selectively vaporise the zinc, providing a filter through which the vaporised zinc passes prior to contacting a condensing surface on which the vaporised zinc condenses to solid zinc, and continuing to treat the alloy until a desired level of dezincing is achieved.
