Acanthite Composition, Characteristics, Properties, Uses
Acanthite and Argentite are often used interchangeably. Both are ores of silver sulfide. Above 173 oC, Argentite is a form of Silver Sulfide. Below this temperature, Argentite changes to Acanthite. At room temperature, Ag2S actually stands for Acanthite. Acanthite Versus Galena. Acanthite and Galena are two most important ores of Silver.
Using salt to refine silver – Colorado Central Magazine
That converted a silver sulfide, hard to separate, into a silver chloride, easy to separate. Sometimes, when the ore was especially rich, droplets of pure silver would form during roasting. The ore had to be pretty rich for this process to pay at all — it wasn't very efficient, and a lot of the silver .
Silver sulfide The Reader Wiki, Reader View of Wikipedia
Silver sulfide (Ag 2S) is the sulfide of silver. It is useful as a photosensitizer in photography. This dense black solid constitutes the tarnish that forms over time on silverware and other silver objects.[8] Silver sulfide is insoluble in all solvents, but is degraded by strong acids. Silver sulfi
