Zinc Ore - an overview | ScienceDirect Topics

Gold recovery from copper– zinc ores is usually higher than that obtained from either a lead–zinc or copper–lead–zinc ore. This is attributed to two main factors. When selecting a reagent scheme for treatment of copper–zinc ores, there are more choices than for the other ore types, which can lead to the selection of a reagent scheme which is more favourable for gold flotation.
