However, Obaje's (2009) suggestion that chemical interaction between the upwelling ore-bearing hydrothermal fluids with the host rock in the saliferous or evaporitic zone may have resulted in the deposition of lead-zinc mineralisation remains a valid possibility. The influence of structural control on the mineralisation processes suggests contributions by …

The document discusses the beneficiation of lead-zinc ores. It reviews different types of lead-zinc ore deposits and beneficiation techniques currently used. Froth flotation is the most widely used technique for beneficiating lead-zinc sulfide ores. The selection of reagents is important to achieve high recovery and grade given the varied mineralogy of ores.
