GALENA? · You would have to ship that ore all the way to Canada to smelt it. Unless it is silaceous ore it is virtually worthless and even then it needs to be 200 OPT and 60% silica to be marketable. With tons of galena laying in piles here that runs 250 OPT or more no one yet has figured out a way to make a profit from it.
Evolution of Silversmelting Technology of Japan in the Middle of ...duced argentiferous galena ore, and is supposed to be the major source of lead supplied to the Iwami silver mine for silver ore smelting. Several furnacelike bowls in the ground were found in 2011 at Tokoya area in Kuki. Slags were col lected from the area, where is the smelting site presumably of the 16th century.

The Mysterious Case of Columbus's Silver Ore · Feb. 15, 2007 Silverbearing ore found at the settlement founded by Christopher Columbus's second expedition was not mined in the Americas, new research reveals. The ore that researchers excavated from the settlement, La Isabela, came from Spain, said Alyson Thibodeau, who analyzed the ores.
Historical Metallurgy of Silver | Articles | Ore concentrate of poor complex sulphidic ore was first smelted to produce so–called matte (solidified melt of metal sulphides, mainly Cu 2 S and FeS). During this process, silie slag was formed that removed the undesirable admixtures (iron, zinc and silies) from the poor ore. Silver was extracted to the matte.
Does galena dissolve? · Galena has a cubic lattice structure and is also a source of silver. The lead in Galena is toxic if inhaled or ingested from dust particles, but the mineral or rock containing the mineral can be handled safely if there is no lead dust .
An early medieval leadsmelting bole from Banc Tynddol, .The ore smelted was predominantly galena but with no detectable silver, showing it was prob ably exploited to produce lead. The extremely high sulphur content of the slag indies that the ore was not roasted before smelting. It is argued that the medieval activity was smallscale, smelting a very rich ore.
Medieval leadsilver smelting in the Siegerland, West Germanyrecovery of both lead and silver during smelting, this would result in about 2000ppm silver in the metal smelted, ie about ten times the amount found in the geological ore samples. Microscopic analyses proved that the ores were dominated by galena and sphalerite, with antimony and silver being bound mostly to the antimonial fahlore tetrahedrite ...
Galena The primary ore of lead that is sometimes mined for its silver .It has a distinct silver color and a bright metallic luster. Galena tarnishes to a dull gray. Because lead is a primary element in galena, the mineral has a high specific gravity ( to ) that is immediately noticed when picking up even small pieces. Galena is soft with a Mohs hardness of and produces a gray to black streak.
Galena The primary ore of lead that is sometimes mined for its silver .Argentiferous galena: Argentiferous galena from Coeur d'Alene, Idaho. Specimen is approximately 21/2 inches ( centimeters) across. Argentiferous galena has a silver content that is often high enough for the galena to be mined as an ore of silver. Some galena mines receive more revenue from their silver than from their lead production.
SmeltingThe ore is now ready for smelting. Mines in Canada There are two ways in which galena can be transformed into lead and each process requires two chemical reactions to occur in the furnace: Process #1 1) 2PbS + 3O2→2PbO + 2SO2 In the first reaction of the first process, galena is roasted in order to remove the sulfur component of the metal sulfide.
Lead in Ancient Peru: the Curamba Smelter and Lead Sling Bulletsancient metallurgical center where silver ore, as argentiferous galena (PbS), was processed. This interpretation was based on the grand scale of silver and other metals produced by ancient Peruvian metallurgists, the loion of the site on a hill so as to take advantage of the winds for smelting, and the presence of numerous depressions ...
GalenaGalena is the main ore of lead, used since ancient times. Because of its somewhat low melting point, it was easy to liberate by smelting. In some deposits galena contains about 1–2% silver, a byproduct that far outweighs the main lead ore in revenue. Occurrences of Galena

Iridium to provenance ancient silver · establishing a relation between chemical analyses on ancient silver objects and mineralogical sources of silver requires not only knowledge of the composition of the ores, but also of how the composition changes during smelting and cupellation (a selective oxidation process where silver is separated from its lessinert lead host) ( pernicka et .
How to Make Lead from Galena Concentrates · How It Works The present method for smelting lead sulfide concentrates to produce lead is a pyrometallurgical smelting method that requires temperatures as high as 1,400 °C. Such smelting methods result in high lead and sulfur dioxide emissions. These hightemperature smelting operations will be unable to meet proposed emission standards.
silver lead ore refining201585 · All silver ores need to be fluxed for In Pliny''s day, when almost all the ore smelted was highgrade, the addition of lead or lead ore (galena, PbS) was sufficient for fluxing (book XXXIII, sec. XXXI).

Paleometallurgy: Assaying galena for silver · Silver chloride is not. It should be a simple matter of dissolving the galena in hydrochloric acid and watching for an insoluble precipitate. Silver chloride has some welldefined characteristics, so it should be easy enough to confirm the silver and estimate the silver content of the original lead.

Silver isotope and volatile trace element systematics in galena . · Argentiferous galena (PbS) is considered by some to be the main source of silver during ancient times (, Domergue, 2008, 1990) with silver having been extracted from PbS by smelting and subsequent cupellation in the presence of metallic lead (, Tylecote, 1992; Pernicka et al., 1998 ).
The Source of SilverThe remainder is obtained by smelting rich ores and refining copper or lead bullion produced. The siliceous silver ores are of varying age, but most epithermal ores are young, typically postMiocene age. Those found chiefly in Colorado, Nevada, and Montana, are associated with Tertiary lavas and characterized by Bonanza grade rich ores.
