OverviewSilver oresHistoryOre processingSee also

Silverbearing ore typically contains very little silver, with much higher percentages of copper and lead. As such, most silver produced is refined from sulfide ores such as galena (lead) or chalcopyrite (copper) which contain small amounts of silver. Many of these ores are mined for their value as sulfide ores, and silver is extracted as a valuable byproduct, however, some ores are mined explicitly for their silver value. Flotation separation is a key step in this complicated process. Silver mineralizes most commonly as arge

Lead  Essential Chemical Industry</h3><p>Uses of LeadAnnual ProductionManufacture of LeadSecondary ProductionAbout half of the world's refined lead comes from lead ore, the other half coming from secondary (scrap) lead sources. China and Australia have the largest amounts of lead ores and are also the largest primary producers of the metal. Canada, US and Peru have smaller but significant amounts of the ores. The most important lead ore is galena (PbS). Other important ores, such as cerrusite (PbCO3) and anglesite (PbSO4), may be regarded as weathered products of galena and are usually found nearer the surface.
