Galena Lead Ore Processing
Galena Lead Ore Processing. Galena is kind of lead mineral with big density 7.4-7.6g/cm3 and gangue density of 2.2-3g/cm3. Its big embedded granule and density difference makes gravity a great beneficiation method to gain high grade galena concentrate. For gravity separation of galena, the separator involved is mainly jigger.

Froth flotation process and its application
Roasting: In this process the sulfide ores are heated to a high temperature in presence of air. Smelting: In this process heat is applied to the ore in order to extract the base metals like silver (Ag), iron (Fe), copper (Cu) etc. Often before roasting, the ore (generally sulfide ores) is partially purified using another important

A review on the electrochemistry of galena flotation
Galena (PbS) is one of the most important base metal sulfide minerals and is a narrow band gap semiconductor. Galena often occurs with other sulfide minerals, such as chalcopyrite or pyrite (Zárate et al., 2012).Oxidation, reagent adsorption, and reactions between sulfide minerals and aqueous solution play a key role in mineral processing (Ralston, 1991).
