lead ore process

Lead processing-Lead processing- Mining and concentrating: Once theoreis removed from veins (narrow channels) or lodes (roughly spherical deposits) in the Earth, usually at depths of about 60 metres, theoreis treated at concentrating mills.

Usually,leadis found in conjunction with other metals such as silver and zinc.Leadmaterials are mined as a by product of these other more valuable metals. Extracting theleadmaterials from theoreis a multi-stepprocess. First thelead oreis ground into small particles that are less than 0.1mm, giving theorea texture similar to table salt.

Lead Oreis found in different places of the world. The Galena orLead Sulphideis the main commercial source of Lead. OtherLead oresinclude Carbonate, Sulphate, Chromate, Phosphate, Chloride and etc. TheLead Oresmay also contain other toxic metals. Lead minerals are separated from gangue and other materials in the ore by dry crushing,...

Lead ores are usually associated with other metals, particularly silver which can be mined at the same time – and zinc, which can cause problems during smelting. The Sulfide Mineral,Galena, aLead sulfide,PbS, is the most important ore mineral of Lead. It can contain 86% Lead.

Theprocessused is froth flotation, a succession of stages each delivering a greater concentration of thelead ore. Theore, containing gangue (which typically contains 3-8%lead) is ground with water to a particle size similar to that of fine sand (<0.25 mm).

Leadis commonly found in deposits with other minerals, such as silver, zinc or copper. Once thelead oreis brought to the surface, it goes through a series of refiningprocessesthat separate out the different metals contained in theore. For example, U.S. mines in Alaska and Missouri are zinc andlead operations.

Lead oresare such that these two operations are best combined into one simultaneousroasting-sintering processthat produces a sinter ready for theleadblast furnace. The second stage of smelting can take place in anorehearth, or a larger blast furnace.

Lead Ore. Lead Ore is found from ores dug from ground mines. Some form of Lead is found in many minerals but the Galena is a one of the most important product for getting Lead. The Galena has only Lead and Sulphar which is called pure Galena.

Lead oreis most commonly found asleadsulphide (PbS), galena, a heavy, shiny grey metallicorewith a conspicuous cubic cleavage, but locally pyromorphite,leadchlorophosphate (Pb 5 (PO 4) 3 Cl), was worked on Green Hill, near Charterhouse and on Blagdon Hill. Around Charterhouse, thelead orecontained small amounts of silver.

Leadis extracted from ores dug from under-ground mines.Leadis also found in conjunction with other metals such as silver and zinc.Leadmaterials are mined as a by- product of these other more valuable metals. Extracting theleadmaterials from theoreis a tediousprocess. First thelead oreis ground into small salt-like particles.

The majority of the deposits are mixtures of minerals, hencelead oreis usually obtained as a byproduct of other metal mining such as zinc, silver or copper. In fact,lead oreis a main source of silver and contributes substantially towards the world's total output. The most commonlead oreis galena (PbS), which contains 86.6%lead.

Primary production from minedlead oreis of course the original source of alllead, but secondary production, where it is recovered from recycled products or from residues arising from the productionprocessis of enormous importance. Secondaryleadproduction now accounts for more than half of allleadproduced throughout the world.

Thus, in alead-zincore, silver is more valuable in theleadthan in the zinc concentrate. Similarly, in a copper orlead orecarrying gold associated with pyrite, it might be profitable to make an iron concentrate containing the gold.
