A review on the electrochemistry of galena flotation

May 01, 2020· When the potential increases, polysulfides can be further oxidised to elemental sulfur. The initial oxidation reaction involves the removal of lead atoms from the sulfide lattice to form a metal-deficient surface layer, which affects the collectorless flotation of galena. The reaction producing lead deficiency is represented by Eq.

Lead Smelting Base Metal Smelting

The process in which galena is smelted requires two important chemical reactions to occur within the furnace. 1) The galena is roasted (reacts with O2) in order to remove the sulfur component of the metal sulfide [2]. Roasting is a method where a sulfide ore (i.e an ore containing PbS) is heated in air which converts the metal sulfide to either

Lead smelting Wikipedia

Galena, the most common mineral of lead, is primarily lead sulfide (PbS).The sulfide is oxidized to a sulfite (PbSO 3) which thermally decomposes into lead oxide and sulfur dioxide gas.(PbO and SO 2) The sulfur dioxide (like the carbon dioxide in the example above) is expelled, and the lead oxide is reduced. Anglesite, Cerussite, Pyromorphite, Mimetite and Wulfenite are other lead ores.

Feb 01, 2014· 1. Introduction. The pyrometallurgical smelting process is the primary route to treat galena concentrates. However, it generates both SO 2 and volatile lead compounds, which may lead to serious environmental problems if not carefully controlled. The conventional smelting process is not well suited to treat complex sulfides or low-grade sulfide ores.

This means removing the waste rock from the lead. Sulfur and galena, known as lead sulfide, are made up a significant component of the mineral. The process of rotation will collect the sulfur-bearing part of the ore that contains as well a valuable metal. The next step is filtering to remove up 90% of the water.
