Sodium thiosulfate is a common analytical reagent used in iodometric titration to analyze chlorine, bromine, and sulfide. Other uses are in bleaching paper pulp, bleaching straw, ivory, and bones, for removing chlorine from solutions, silver extraction from its ores, a mordant in dyeing and printing textiles, and as an antidote to cyanide poisoning. [Pg.881]

Pre-Roman lead does not appear to have been de-silverised, but the Romans certainly knew how to abstract the silver by cupellation (p. 190) long before they invaded Britain. Probably they worked lead ores with the dual object of obtaining both silver and lead. Many Roman lead pigs bear the inscription ex arg, that is, silver extracted. Analysis of Roman pigs show their silver contents to have often been very low. The following silver contents from... [Pg.189]

In Mexico, ores are available containing pyragyrite and proustite, mined entirely for silver extraction, and Mexico derives 50% of its silver production from mines containing these so-called primary silver minerals The other half is, as in the rest of the world, a by-product of copper, zinc and lead production. [Pg.134]
