    Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point. At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific measures are taken to prevent it. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphale

  • Separation of Lead-Zinc by Froth Flotation Metallurgy

    Froth flotation is the main process used to separate lead-zinc minerals from each other as well as from gangue. It is effectively applied for the concentration of Pb-Zn ores, but technically, it differs from one deposit to another due to gangue changes, mineral association and liberation size.

  • Surface chemistry investigation of froth flotation

    In the mineral processing industry, lead-zinc sulfide ores are usually processed by froth flotation to enrich the purpose minerals . Flotation is a complex process, and the selective separation of minerals depends on the balance between the hydrophilic species
