lead mineral extraction
Lead Wikipedia
Many lead minerals are relatively light and, over the course of the Earth's history, have remained in the crust instead of sinking deeper into the Earth's interior This accounts for lead's relatively high crustal abundance of 14 ppm; it is the 38th most abundant element in the crustLongwall mining allows for increased mineral extraction to occur, since it shears entire blocks of mineral onto a conveyor belt through the use of selfadvancing, hydraulic roof supports or shields Once the mineral is extracted, the supports move on and the roof is allowed to collapseMineral Extraction The Environmental Literacy CouncilLEAD PRODUCTION IN THE WORLD : The largest producer of lead materials in the world is Australia followed by the USA, China and Canada Lead is extracted from ores dug from underground mines Even though more than 60 minerals contain lead, only Lead Mining TechniquesMetal ExtractionUses Of Chemical

LEAD INDUSTRY PROFILE
naturally occurring minerals which contain lead, the most important ore (mineral suitable for the extraction of the metal) is galena (lead sulphide, PbS); other ores include cerrusite (lead carbonate, PbCO 3) and anglesite (lead sulphate, PbSO 4), which are generally found in small amounts nearer the surface of sulphide depositsA major and primary Lead mineral is galena (PbS) which comprises of 866% of lead In order to smelt this mineral, a blast furnace is needed to be used A blast furnace is an enormous oven which is used to accomplish the smelting processes According to their properties and applications, lead alloys can be classified into: corrosion resistant Lead: smelting, producing and classificationMetalpediaBolivia’s Mineral Extraction Index: Lead data was reported at 449500 1990=100 in Dec 2016 This records an increase from the previous number of 378010 1990=100 for Dec 2015 Bolivia’s Mineral Extraction Index: Lead data is updated yearly, averaging 100490 1990=100 from Dec 1992 to 2016, with 25 observations The data reached an alltime Bolivia Mineral Extraction Index: Lead Economic Indicators

Lead is a very corrosionresistant, dense, ductile, and malleable bluegray metal that has been used for at least 5,000 years Early uses of lead included building materials, pigments for glazing ceramics, and pipes for transporting water The castles and cathedrals of Europe contain considerable quantities of lead in decorative fixtures The —3/8″ fraction goes by gravity to a Mineral Jig which produces a final jig concentrate from the slimy — 3/8″ mill product This jig, due to its selective action saves the fine mineral as well as the coarse sizes Very coarse lead minerals, if present, can be discharged by means of a center draw Oxide Lead Treatment Extraction by Flotation naturally occurring minerals which contain lead, the most important ore (mineral suitable for the extraction of the metal) is galena (lead sulphide, PbS); other ores include cerrusite (lead carbonate, PbCO 3) and anglesite (lead sulphate, PbSO 4), which are generally found in small amounts nearer the surface of sulphide depositsLEAD INDUSTRY PROFILE
