目前已知在美国有一些从金和银含量比较高(Au1.7g/t、Ag60g/t)的剥离岩石和围岩中回收金和银的实例,以及智利从这些物料(Ag160g/t)中回收银的实例。本文研究了从不同成分的几种贫的剥离岩石和围岩(Au0.1—0.5 g/t、Ag约1.0g/t)中回收金和银的可能性。
It is currently known in the United States that there are some examples of the recovery of gold and silver from exfoliated rocks and wall rocks of relatively high gold and silver (Au 1.7 g / t, Ag 60 g / t) and the recovery of gold and silver from these materials (Ag 160 g / t) Recycling silver example. This article investigates the possibility of recovering gold and silver from several poorly peeled rocks and surrounding rocks of varying composition (Au 0.1-0.5 g / t, Ag 1.0 g / t).
