Silver was first obtained in sixteenth-century Mexico by a method called the patio process. It involved mixing silver ore, salt, copper sulphide, and water. The resultant silver chloride was then picked up by adding mercury. This inefficient method was superseded by the von Patera process. In this process, ore was heated with rock salt, producing silver chloride, …

Silver can be prepared by extraction through the cyanide process. Let us understand about the process in more detail: Extraction of silver by the cyanide process. Silver is also found in the combined and free states. The most important silver-ore minerals are argentite (Ag2S), copper-look silver, ruby silver, horn silver.

Dental alloys of 60–70 percent silver, 18–25 percent tin, 2–14 percent copper, and 0.5–2 percent zinc are amalgamated with varying quantities of mercury to form the filling materials for cavities in teeth. Silver and alloys of silver and copper, although stable in air, tarnish in the presence of sulfur.

The patio process is a process for extracting silver from ore. Smelting, or refining, was necessary because silver does not occur by itself in a natural state like some metals. Instead, it is made up of a larger ore body. Thus, smelting, or refining, is necessary to remove other byproducts to get at pure silver. [1]

Silver is a soft, white metal that usually occurs in nature in one of four forms: 1) as a native element; 2) as a primary constituent in silver minerals; 3) as a natural alloy with other metals; and, 4) as a trace to minor constituent in the ores of other metals. Most of the silver produced today is a product of the fourth type of occurrence.
