flotation of lead zinc ores

Chapter 14: Flotation of Lead-Zinc Ores | Engineering360

 · Lead-zinc ores are the most abundant ores in the world and they are found in everywhere, such as North America, South America, Balkan Peninsula, Europe, Russia, Australia and Africa. There is a fairly large variety of ores, ranging from carbonatite ores that are relatively easy to treat to refractory ores, where a treatment process has yet to be fully developed.

Effects of Process Parameters on Selective Flotation of Lead-Zinc Ore

The present work was undertaken to study the effects of various process parameters on concentration of a typical lead-zinc ore sample by froth flotation. Prior to flotation studies, the sample was characterised with respect to chemical and mineralogical characteristics. The basic flotation scheme adopted for concentration of the lead-zinc ore sample consisted of differential flotation separation by depression of zinc bearing minerals using a combination of sodium cyanide and zinc sulphate as depressant and flotation of lead minerals using potassium ethyl xanthate as collector and methyl iso-butyl carbinol (MIBC) as frother. Lime was used as pH regulator and this also helped in depression of pyrite. Subsequently zinc was floated …
