A study on lead extraction from lead concentrate had been conducted. Galena is usually associated with other sulfideores such as sphalerite.The lead concentratewas able to be extracted and purified into its metal througha leaching process using a selective solvent fluosilicic acid (H 2SiFof 6).

Galena: The mineral galena information and pictures

Galena is by far the greatest ore of lead. The extraction process to remove the lead from the sulfur is very simple, thus lead has been extracted from Galena since the earliest times. Galena from certain regions is rich in silver, and some specimens may contain as much as 20 percent silver. Because of this, silver-rich Galena is also an ore of silver. . Another use of Galena was its importance ...

Galena Mineral | Uses and Properties

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.
