Silver is found in a native form very rarely as nuggets in placer deposits and veins. It is more commonly combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag 2 S), chlorargyrite ("horn silver," AgCl), and galena (a lead ore often containing significant amounts of silver). As silver is often found in conjunction with these or alloyed with other metals ...
Mercury processing, preparation of the ore for use in various products.. Mercury (Hg) has a unique combination of physical properties. Its low melting point (−38.87 °C [−38 °F]) and boiling point (356.9 °C [674 °F]), high specific gravity (13.5 grams per cubic centimetre), uniform volume expansion over the entire range of temperatures in its liquid state, and high surface tension (so ...

Silver Recovery Equipment, Which One is Best for You? That best silver recovery equipment for you depends on the following factors: 1) Your processing volume, whether or not you want to reuse your fixer or bleach-fix, and environmental concerns, such as strict limits on effluent discharge. 4) The operating and refining costs.
Silver is a chemical element with the symbol Ag (from the Latin argentum, derived from the Proto-Indo-European h₂erǵ: "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver ...

Silver is the main metal in e-waste recycling. If you have silver in metal form then you can easily melt this. But if you have silver in powder form like silver chloride then you can face many problems in melting silver. As usually, silver melts at 961 C and this temperature point is less than gold melting but melting silver is hard and technical.
