lead and zinc ores its uses and occurrence

Carbonate hosted lead zinc ore deposits are important and highly valuable concentrations of lead and zinc sulfide ores hosted within carbonate limestone, marl, dolomite formations and which share a common genetic origin These ore bodies range from 0 5 million tonnes of contained ore, to 20 million tonnes or more, and have a grade of between 4 combined lead and zinc to over 14 combined

Copper, its occurrence, and use A What is copper? Copper is a chemical element in the periodic table with the symbol Cu from the Latin word cuprum, meaning metal of Cyprus, where it was mined during the Roman era Copper has an atomic number of 29 and atomic weight of 63 54 grams per mole It is an element in Group 11 of the periodic table, sharing many properties with silver and gold

Nearly all zinc sulphide ores carry some lead the western ores of zinc generally carry silver, and some of them carry both silver and gold but so far as the records show its occurrence in western deposits is rare Utah, valuable bodies of oxidized zinc ore are found on the borders of older sulphide deposits In this district and at

Apr 30, 2018 Natural occurrence of lead is very rare it is found in ores with zinc, copper, and silver, and is later extracted from these elements Apart from the above, there are also other miscellaneous uses of lead Some of the other beneficial uses for lead have been listed below

History of Zinc Centuries before zinc was discovered in the metallic form, its ores were used for making brass and zinc compounds for medicinal purposes Zinc compounds were in the ores smelted certainly as early as 200 B C to obtain copper and which gave alloys of copper and zinc

Zinc Mining The most commonly available ore used in the extraction of Zinc is called Zinc Blende also known as Zinc Sulphide ZnS Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas

Lead and Zinc Lead and zinc ores are usually found together with gold and silver A lead zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals The remaining rock and minerals are called gangue

Zinc sulfate, ZnSO 4, is an intermediate compound in the production of zinc from its ores by the electrolytic process It is used as a weed killer, in the manufacture of viscose rayon, and in dyeing, in which it functions as a mordant

For this reason, zinc lead blast furnace utilizes a sintering process to supply its oxidized feed Fine ores are mixed with crushed returned sinter to give a material containing about 6 5 percent sulfur This is fed onto a moving grate and fired in an updraft of air, and the sintered cake leaving the machine is broken into a convenient bulge

Lead is easily extracted from its ores prehistoric people in Western Asia knew of it Galena, a principal ore of lead, often bears silver, interest in which helped initiate widespread extraction and use of lead in ancient Rome Lead production declined after the fall of Rome and did not reach comparable levels until the Industrial Revolution

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
