  • Silver: A native element, mineral, alloy, and byproduct

    Most of the silver produced today is a byproduct of mining copper, lead, and zinc. The silver occurs within the ores of these metals in one of two ways: 1) substituting for one of the metal ions within the ore mineral's atomic structure or, 2) occurring as an inclusion of native silver or a silver mineral within the ore mineral.

    There are two general classes of silver ore that have been mined: 1) leadsilver and 2) highgrade silver ores. Both have almost always varying amounts of gold. The lead silver mines furnish also, as noted above, by far the greater portion of the lead produced in the United States.

  • How to Identify Silver Ore Our Pastimes

    Lead can be a dark gray to black colored ore. Watch for areas of quartz deposits. Quartz is considered the host rock for many silver deposits. Quartz is a crystalline structure that has a white to clear appearance. Bright white quartz with streaks of gray are a good indicator of the presence of silver ore. Inspect each rock carefully since some silver deposits will be barely

  • Gold and Silver Leaching by Cyanidation

    Introduction to Gold and Silver Leaching. The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890.

  • Silver mining Wikipedia

    Silver mining is the resource extraction of silver by mining. Silver is found in a native form very rarely as nuggets, but more usually combined with sulfur , arsenic , antimony , or chlorine and in various ores such as argentite (Ag 2 S ), chlorargyrite ("horn silver," Ag Cl ), and galena (a lead ore often containing significant amounts of

    Silver is found in lead, zinc, gold and copper ore deposits. The most important ore mineral of silver is argentite (Ag2S, silver sulfide). Silver is commonly extracted from ore by smelting or chemical leaching. Uses. Silver has been used for thousands of years for jewelry and decorative items of all types. Likewise, it has been used for silverware.

    Silver extraction from stephanite improved to 98% by adding lead nitrate directly to the leaching stage, whereas pyrargyrite required a pretreatment with lead nitrate to extract 83.2% Ag. With the addition of lead nitrate, the mineral surfaces had a PbO species and minor amounts of Pb(OH)2 and antimony was oxidized on the stephanite and pyrargyrite surfaces during leaching.

    The silver occurs associated with manganese and lead in veins, stockworks, and mantotype deposits in the Mississippian Leadville Limestone (here a dolomite), the Devonian Dyer Dolomite, and the Ordovician Manitou Dolomite. Ore minerals are pyrite, sphalerite, and galena, in jasperoid and manganosiderite gangue.
