氖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 minerals.It crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite
Read MoreLead ore is most commonly found as lead sulphide (PbS), galena, a heavy, shiny grey metallic ore with a conspicuous cubic cleavage, but locally pyromorphite, lead chlorophosphate (Pb 5 (PO 4) 3 Cl), was worked on Green Hill, near Charterhouse and on Blagdon Hill. Around Charterhouse, the lead ore contained small amounts of silver.Metallurgy of Lead . Ores. 1. Galena PbS 2. Cerrusite PbCO 3 . 3. Anglesite PbSO 4 . 4. Lead ochre PbO. Extraction: Lead is mainly extracted from the sulphide ore galena. Galena contains lead sulphide and small quantities of silver.. 1. Concentration: The ore is concentrated by froth floatation process. 2.
Read MoreLead found as lead sulphide in nature. Its ore is Galena, which is a heavy, shiny grey, metallic ore. Galena comprises 86 percent of lead. Process of extracting lead from ore: Galena is roasted, which converts the lead sulphide into lead oxide. The formed lead oxide is made to react with coke to attain refined lead.The oxide lead ore in a dolomitic matrix may contain clay slimes and a fairly large amount of pyrite and barite; both of these minerals have a negative effect on oxide lead flotation. These ores may contain one or several lead minerals, including cerussite, anglesite and pyromorphite. Some lead oxide ore varieties may contain oxide copper ...

Research to better understand the geologic processes that form mineral deposits, including those containing lead, is an important component of the USGS Mineral Resources Program.Write the chemical equations involved in the extraction of lead from galena by self-reduction process. asked Jun 25, 2019 in Chemistry by xD4y4 ( 66.9k points) class-11
Read MoreLead is hardly obtained from lead ore anymore, however, but instead from recycled lead scrap. Today, more than 50 per cent of global requirements can be met from this.Ores are naturally occurring rocks that contain metal or metal compounds in sufficient amounts to make it worthwhile extracting them. For example, iron ore is used to make iron and steel. Here, we providing a List of some Important metals and their ores. it is mainly useful for your upcoming competitive exams like SSC, UPSC etc.
Read MoreAnswer (1 of 6): In the mining industry ore is used commonly at mining operations to indicate material that you plan on mining, or have mined and are sending to process. It also has another use. In any public release of information by a company, "Ore" has a very special and particular meaning. O...A) Galena, also called lead glance, is the natural mineral form of lead(II) sulfide.(PbS). B) Anglesite is a lead sulfate mineral with the chemical formula P b S O 4 . C) Cerussite (also known as lead carbonate or white lead ore) is a mineral consisting of lead carbonate (P b C O 3 ), and an important ore of lead.
