摘要

The content and distribution of silver in laminated lead alloy anodes have a significant impact on the costrnand performance of zinc electrowinning processes. Typical Ag contents in anodes used by zinc producersrnare known to vary between 0.25 to 1.0% wt Ag. Although lowering Ag content can represent significantrnoperational cost savings, it increases the requirement for uniformity of micro-scale Ag distribution.rnQuantitative metallographic methods have been developed to improve the replicability and reproducibilityrnof micro-scale Ag distribution measurements. The results are being used to assess and optimize laminatedrnanode manufacturing procedures.
