3. Lead-bearing Silver ores: These are silver ores containing 4 percent or more of lead. The silver comes mainly from the lead-silver ores of Coeur dAlene, Idaho, Utah (chiefly Park City and Tintic), Colorado (Leadville and Aspen). Most of the output is obtained …
Silver sulfide - Wikipedia
Silver sulfide is the inorganic compound with the formula Ag 2S. A dense black solid, it is the only sulfide of silver. It is useful as a photosensitizer in photography. It constitutes the tarnish that forms over time on silverware and other silver objects. Silver sulfide is insoluble in most solvents, but is degraded by strong acids. Silver sulfide is a network solid made up of silver (electronegativity of 1.98) and sulfur (electronegativity of 2.58) where the bonds have low ionic character (approximately 10%).
How To Smelt A Gold Button By Roasting Sulfide ...
22-08-2018 · In this video, we show the process of smelting down sulfide-rich gold concentrates to end up with a gold button. Through roasting, the sulfur is driven off, in turn, converting the metallic ...
Sulfide Ores - an overview | ScienceDirect Topics
Sulfide ores are frequently associated with a range of important metals, most notably copper, lead, nickel, zinc, silver, and gold. From: Treatise on Geochemistry, 2003 Related terms:
The Mineral Gallery - Sulfides Class
The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.
Silver - Wikipedia
It mostly occurs in sulfide ores, especially acanthite and argentite, Ag 2 S. Argentite deposits sometimes also contain native silver when they occur in reducing environments, and when in contact with salt water they are converted to chlorargyrite (including horn silver), AgCl, which is prevalent in …

Smelting and Roasting Ores to recover gold, silver …
When smelting assays are done on high sulfide ores, a couple of iron nails are added to the mix. The metal in the nails reacts with the metals in the sulfides reducing the metals to their metallic state. This is handy when processing silver containing minerals to convert them to silver metal.
PRESSURE OXIDATION OF REFRACTORY GOLD ORES: THE …
Pressure oxidation is employed to liberate gold and silver in refractory sulfide concentrates often and ores. The main pressure oxidation products from iron sulfide minerals are sulfuric acid (and metal sulfates) and hematite. Depending on the conditions within the …
Silver: A native element, mineral, alloy, and byproduct
Native silver is sometimes found in the oxidized zones above the ores of other metals. It persists there because silver does not readily react with oxygen or water. It does react with hydrogen sulfide to produce a tarnished surface that is composed of the silver sulfide mineral known as acanthite.

Distribution of silver in massive sulfide ores | …
Abstract. The distribution of silver in connection with the formation of massive sulfide ores is discussed. It is proposed: 1) The affinity between silver and galena-rich ores is only pronounced if antimony and/or bismuth are also present in significant amounts, and 2) The degree of correlation between silver and lead is partly a function of the Ag/Sb+Bi ratio in the ore and increasing with ...
