Silver: mineral and native element overview

Silver can be found as a primary mineral in certain hydrothermal veins, and in volcanic basalt rocks. It also forms as a secondary mineral by breakdown of polymetallic ore deposits. Many highly priced silver specimens were formed by decomposition of primary silver-bearing minerals.

Clear Creek County Colorado Gold Production

The most abundant minerals of the silver-lead-zinc ores are galena, sphalerite, and pyrite. These ores commonly contain less than 0.10 ounce of gold per ton. The chief gangue minerals are quartz and brown carbonates. The principal minerals in the pyritic gold deposits are pyrite, chalcopyrite, gold, small amounts of silver minerals, and quartz ...
