Chapter 14: Flotation of Lead

Most of the lead-zinc ore contains silver and to a lesser degree, gold. Almost 85% of the silver production in the world comes from lead-zinc ores. Silver recovery in a large number of ores, specifically from South America, is emphasized, and some of these circuits were in fact designed to provide the highest possible silver recovery.
