(Agricola, p. 232) All silver ores need to be fluxed for smelting.6 In Pliny's day, when almost all the ore smelted was high-grade, the addition of lead or lead ore (galena, PbS) was sufficient for fluxing (book XXXIII, sec. XXXI). By the time that Biringuccio and

DF2014:Galena - Dwarf Fortress Wiki

2021-1-29  Galena can also be used in alloy reactions requiring silver-bearing ore. Because these reactions treat the galena nugget as the equivalent of 4 silver bars, the resulting alloy will show a roughly 30% increase in value over smelting the galena separately. Galena is also magma-safe, but just barely. Since galena is a mid-value ore

Processing Ore - The Smelt Mill • Lead Mining in the ...

The smelting process is essentially very simple. Pellets of Galena are heated until they reach melting point. Because lead has a low melting point any impurities are not melted and are left as waste. The molten lead can be allowed to drain from the fire hearth into a collecting pot and then poured into moulds to form blocks of pure lead metal.

Galena Ore The Story of Illinois

Lead is a soft metal with a low melting point that can be quite easily extracted from the ore by smelting. Lead sometimes contains silver and other metals that can be separated in the smelting process. This sample of galena ore in the Illinois State Museum Legacy Collection is from Jo Daviess County, where the town of Galena is located.

The primary ore is galena or Lead sulphite PbS. This is unstable, and on prolonged exposure to the atmosphere it oxidizes into the minerals cerussite PbCO3 and anglesite PbSO4. Lead ores are usually associated with other metals, particularly silver which can be mined at the same time – and zinc, which can cause problems during smelting.
