The chemical symbol for silver is Ag, from the Latin argentum, which means white and shining. Although silver does not react to many chemicals, it does react with sulfur, which is always present in the air, even in trace amounts. The reaction causes silver to tarnish, therefore, it must be polished periodically to

Silver processing - The metal and its alloys Britannica

2020-8-15  Silver processing - Silver processing - The metal and its alloys: Even silver that has been fully work-hardened, either by rolling or forging, gradually recrystallizes, even at room temperature. This greatly softens the metal, making it susceptible to scratching and marring. To maintain hardness, therefore, other metals are added to form alloys that are harder, stronger, and less prone to fatigue.

Heap Leaching of Gold and Silver Ores - ScienceDirect

2016-1-1  Silver is usually not as reactive as gold with cyanide. This is because gold almost always occurs as the metal, whereas silver may be present in the ore in many different chemical forms, some of which are not cyanide soluble. Gold recovery efficiency from operating heap leaches is typically ∼70%, although it can range from 50% to 90%.

ACANTHITE/ARGENTITE (Silver Sulfide)

Acanthite is the most important silver ore next to galena.Actually there is an argument to be made that acanthite could be the most important silver ore. Galena is a lead ore that often contains enough silver (usually about 1%) that when it is processed for its lead content the by-product silver supplies the majority of the world's needs. But most, if not all the silver in argentiferous galena ...
