Process Large scale cupellation. Native silver is a rare element, although it exists as such. It is usually found in nature combined with other metals, or in minerals that contain silver compounds, generally in the form of sulfides such as galena (lead sulfide) or cerussite (lead carbonate). So the primary production of silver requires the smelting and then cupellation of argentiferous lead ores.Overall recoveries achieved in 2019 production at the Galena processing plant were approximately 95% for silver and 92% for lead. Although only a silver-lead concentrate is currently produced, the LOMP does include future mining from the silver-copper veins, at which time a silver- …
