ore of lead sulfide

Lead-zinc deposits are generally accompanied by silver hosted within the lead sulfide mineral galena or within the zinc sulfide mineral sphalerite Lead and zinc deposits are formed by discharge of deep sedimentary brine onto the sea floor (termed sedimentary exhalative or SEDEX) or by replacement of limestone in skarn deposits some Sep 16 2012Help with General Chemistry?!? 1 A 2 086-g sample of a compound contians 0 884g of cobalt 0 482 g of sulfur and 0 720 g of oxygen What is its simplest formula? 2 An ore of lead is 45 0% pure lead sulfide PbS and 55 0% impurities in which no other lead compounds are present What mass of lead is contained in 150 0 grams of this one?

Reading Ore Genesis

Lead-zinc deposits are generally accompanied by silver hosted within the lead sulfide mineral galena or within the zinc sulfide mineral sphalerite Lead and zinc deposits are formed by discharge of deep sedimentary brine onto the sea floor (termed sedimentary exhalative or SEDEX) or by replacement of limestone in skarn deposits some

The structure of Galena is identical to that of halite NaCl The two minerals have the same crystal shapes symmetry and cleavage Some Galena may contain up to 1% silver in place of lead The large volume of Galena that is processed for lead produces enough Silver as a by product to make Galena the leading ore of Silver

The majority of the deposits are mixtures of minerals hence lead ore is usually obtained as a byproduct of other metal mining such as zinc silver or copper In fact lead ore is a main source of silver and contributes substantially towards the world's total output The most common lead ore is galena (PbS) which contains 86 6% lead

Galena forms in low- and medium-temperature ore veins along with other sulfide minerals carbonate minerals and quartz These can be found in igneous or sedimentary rocks It often contains silver as an impurity and silver is an important byproduct of the lead industry

to-lead ratio telluride-sulfide mineral assemblages near surface to copper and higher zinc/lead sulfide ores in the deepest skarns Hasler et al (1991) and Gonzales (1988) describe the sediment-hosted high temperature carbonate replacement deposits (CRD) and skarn sulfide mineralization in more detail

A process of recovery of lead from a lead sulfide concentrate In this process a furnace charge is prepared comprising the lead concentrate a source of elemental iron and a source of available oxygen capable of reacting with the sulfur of the concentrate to form an oxysulfide matte The relative proportions of the concentrate source of elemental iron and source of oxygen are such that the

May 02 2014SEDEX (SEDimentary Exhalative) deposits are one of several types of sediment-hosted lead-zinc deposits Rich accumulations of lead zinc and silver are found in the ore minerals sphalerite (zinc sulfide) and galena (lead sulfide) deposited between thin layers of marine sand silt and mud in sedimentary basins

Lead sulfide - definition of Lead sulfide by The Free Define Lead sulfide Lead sulfide synonyms Lead sulfide pronunciation Lead sulfide translation English dictionary definition of Lead sulfide A city of extreme northwest Illinois on the Mississippi River It was a prosperous port and the center of a lead-mining region during the 1800s

Feb 20 2017To begin the ore must be crushed into very small pieces The ore is ground at the mill leaving it in particles with diameters of 0 1 millimeter or less 5 Flotation • The principal lead ore galena is properly known as lead sulfide and sulfur makes up a substantial portion of the mineral

The smelter for sulfide ores produces sulfur dioxide gas This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores Scrubbing sulfur dioxide also protects the environment For example FeO(s) + SiO 2 (s)→ FeO SiO 2 (slag) This is

Rebellious Ores Sulfides Selenides and Tellurides

In many locations where they had initially been recovering 90% of the assay values processing oxidized surface ore with the rebellious sulfide ores they were recovering less than 50% The rest of the precious metals in their ore simply flowed uselessly out from the mill and into the tailings pond

Galena a lead sulfide (PbS) is heavy brittle and breaks into cubes Sphalerite is a zinc sulfide (ZnS) mineral that is brownish yellowish or black It ordinarily occurs with galena and is a major ore of zinc The iron sulfide pyrite (FeS) which is also called fool's gold is common in nearly all types of rocks

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 easy
