Isabela were attempting to recover silver from galena by cupella-tion. The galena was reduced to metallic lead, a process that requires only that crushed ore be sprinkled on a bonfire of stacked wood 3. Sulfur is removed as sulfur dioxide fume, while any silver content dissolves into the metallic lead. Cupellation is the second

Lead-silver ore was discovered in an outcrop on this property in 1887, four years after the initial discovery of precious metals in the Coeur dAlene Mining District. For the next 30 years, ore was mined from a series of surface tunnels and in 1917 the Day brothers started sinking what is now known as the Galena

The crushed ore is then hoisted to the surface in skips or driven directly to the surface by truck via a spiral access tunnel decline. Most of Australias silver is produced from silver-bearing galena, but some also is produced from copper and gold mining. Processing. At the surface, the ore is subjected to additional crushing and fine grinding.

Sometimes the layered ore includes silver black , a black coloured band of mineral aggregates composed of electrum gold and silver alloy, sulphides of silver, chalcopyrite, galena, sphalerite, tetrahedrite and pyrite and clay minerals. Gold and silver concentrations in silver black are quite high.
Oct 17, 2016 The treatment of the first type of ore depends on the manner in which the gold and silver are associated with the sulphide minerals. The cyanide-agitation process is usually the most suitable method of extraction, but it often necessitates grinding to a fine size to release the gold and silver.
Galena will oxidize or tarnish to a dull grey when exposed to the elements. It has a specific gravity of around 7.5, which makes it fairly heavy and dense. In crystalline form galena exhibits cubic crystals. It often contains small amounts of silver. Bornite. Bornite is another important ore of copper.
