Mar 25, 2020· Highly fractured porphyry is known to be the most mineralized, and preliminary work shows a correlation of fractured porphyry with gold, in contrast to unfractured and unmineralized rocks within mineralized zones. This, however, may be due again to gold-bearing sulfides occurring as the primary economic mineral.

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.
