The silver obtained by electrolysis usually has a purity of three-nines fine; on occasion it may be four-nines fine, or 99.99 percent silver. From lead concentrates. Lead concentrates are first roasted and then smelted to produce a lead bullion from which impurities such as antimony, arsenic, tin, and silver must be removed.
Annually, millions of tons of lead and silver concentrates are produced using flotation processes from ores. Xanthates are used as collectors to recover minerals containing lead and silver in conventional flotation plants. However, many flotation plants suffer from reduced lead-silver recovery during their processes. This work examined the promoted flotation of oxidized lead …

The aim of this investigation was to study the oxidative leaching of lead and silver from a lead–silver concentrate containing galena, sphalerite, pyrite and argentite in nitric acid solutions above the melting point of sulfur (119. °C).. The elemental sulfur formed was expected to agglomerate, thereby slowing its oxidation to sulfate and inhibiting the precipitation of lead …
