Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver.. Galena is one of the most abundant and widely distributed sulfide crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite
Lead commonly occurs in mineral deposits along with other base metals, such as copper and zinc. Lead deposits are broadly classified on the basis of how they are formed. Lead is produced mainly from three types of deposits: sedimentary exhalative (Sedex), Mississippi Valley type (MVT), and volcanogenic massive sulfide (VMS). Get Price

Lead oxide ore, mainly in the form of cerussite and anglesite, is originated from primary lead sulfide ore which gradually changed its property under efflorescence and carbonate salt environment. In a lead deposit, lead oxide and lead sulfide usually is detected at the upper layer and lower layer separately.
Lead (II) sulfide may be released to the environment during the mining and processing of galena, the major commercial lead ore (1). Lead (II) sulfide's manufacture and use in semiconductors, infrared detectors, and ceramic glazes (2) may result in its release to .
01/01/2021 · The leadzinc sulfide ore sample was supplied by the Fankou leadzinc mine, Guangdong Province, China. The chemical analysis results of the sample are shown in Table 1 . In the Fankou leadzinc deposit, the main sulfide minerals are galena (PbS), sphalerite (ZnS), and pyrite (FeS 2 ), and the main gangue minerals are quartz (SiO 2 ) and calcite ...
Lead(IV) and sulfide ions are large and polarizable, making them soft in the context of hard/soft acid/base theory (HSAB), which states that ions with similar hardness will form stronger bonds. The oxide ion is hard and therefore has a tendency to form weaker interactions with Pb(IV).
EXTRACTING METALS FROM SULFIDE ORES. Many important metals are present in nature combined with sulfur as metal sulfides; these include cadmium, cobalt, copper, lead, molybdenum, nickel, silver, and zinc. In addition, gold and platinum group metals are associated with sulfidic base metal ores. The extraction of metals from their ores has been an ...
