According to a google search sulfur is widely available in nature. Volcanic regions and hot springs are common sources of it in elemental state. Less obvious sources are iron pyrites (iron sulfide), galena (lead sulfide), gypsum (calcium sulfate), Epsom salts (magnesium sulfate) and many other minerals. Silver ore can be identified in the field by evaluating the physical properties of the suspected sample or by submerging it in water. It is also identified by examining the other minerals found around the suspected ore deposit. 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. Silver often occurs as a minor constituent in the ores of copper, lead, and zinc. Refinement of these metals yields large quantities of silver (and some gold). Silver is found in minute quantities in seawater. The atomic weight of silver is 107.868, and natural silver consists of two stable isotopes: silver-107 (51.82%) and silver-109 (48.18%).

Of the 1740000 metric tons of silver discovered to date, 55% is found in just four countries on earth. Where can I find information about mineral commodities?

Silver is sometimes encountered in pure form. It also is mined from the minerals acanthite (silver sulfide) and stephanite. Silver also is found in the common minerals chlorargyrite (silver chloride) and polybasite. Silver is mined in many countries, but most comes from the USA, Canada, Mexico, Peru and Bolivia. Silver is found in native form, combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag2S) and horn silver (AgCl). The principal sources of silver are copper, How to Detect Silver in the Ground at a Silver Mine Silver is a precious metal located throughout the world in geological deposits. Colorado's state nickname is the "Silver State" due to the large deposits of silver ore found there. Silver is extracted from the ore by a smelting or leaching procedure.

31 Dec 2019 Silver is sometimes found free in nature but it is usually found in ores containing gold, lead, or copper. Early Greeks and Romans used silver to
