    Lead processing, preparation of the ore for use in various products Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury) Its low melting point of 327 °C (621 °F), coupled with its easyLead processing Lead processing Mining and concentrating: Once the ore is removed from veins (narrow channels) or lodes (roughly spherical deposits) in the Earth, usually at depths of about 60 metres, the ore is treated at concentrating mills Here the ore is finely crushed, sometimes to particle diameters of less than 01 millimetre (0004 inch), and then treated by one of several mineralLead processing Mining and concentrating | BritannicaMINING AND PROCESSING : Lead is known to naturally occur in free form in nature, but is generally obtained from the ores galena(PbS), anglesite (PbSO 4), cerussite (PbCO 3) and minum (Pb 3 O 4) It is never considered to be a rare element even though it makes up only about 00013% of the earth's crust since it is easily mined and refined Lead is extracted from ores dug from underground minesLead Mining – Concentration process, flotation, filtering

    Many lead minerals are relatively light and, over the course of the Earth's history, Alternatively to the pyrometallurgical processes, very pure lead can be obtained by processing smelted lead electrolytically using the Betts process Anodes of impure lead and cathodes of pure lead are placed in an electrolyte of lead fluorosilicate (PbSiF 6) Once electrical potential is applied, impureThe lead, zinc and copper veins on Mendip were deposited by hot mineralising fluids (typically between 50 and 150° C) rising up from depth and depositing various minerals as they cooled The source of the fluids were the deep sedimentary basins either side of the Mendips As the Triassic and Jurassic sediments in these basins were buried, compacted and heated over time, some of the water inLead ore and mines | Minerals and mines | Foundations ofThe two principal minerals containing lead and zinc are galena and sphalerite These two minerals are frequently found together along with other sulfide minerals, but one or the other may be predominant Galena may contain small amounts of impurities including the precious metal silver, usually in the form of a sulfide When silver is present in sufficient quantities, galena is regarded as aLead and Zinc Energy
