smelting galena silver ore

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.

(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

Galena an overview ScienceDirect Topics

The association of silver with lead minerals, in particular galena [PbS], is well known and documented, but gold is also frequently found in lead concentrates, and its recovery follows closely that of silver. 5.1 Smelting Processes. Galena concentrates are usually smelted to produce lead bullion. Smelting techniques are numerous, ranging from the traditional blast furnace to the more recent Kivcet, QSL,
