- Silver occurs uncombined, and in ores such as argentite and chlorargyrite (horn silver). However, it is mostly extracted from lead-zinc, copper, gold and copper-nickel ores as a by-product of mining for these metals.

Silver Nitrate Uses â and amazing, interesting facts For example: White=Chloride, Pale Yellow=Bromide, Yeloow=Iodide. Test for the presence of Carbonate, Hydroxide, Sulfide and Phosphate ions. For example: Pale Green=Carbonate, Brown=Hydroxide, Black=Sulfide. Silver Nitrate is used to test the exact salinity of Sea Water.(it's about 35 grams per Liter, by the way...). Silver Nitrate is used in Oil Fields to determine the amount of Chloride ions in water and drilling fluids. In Manufacturing. Silver Plating-electroplating Silver onto a base metal such as Nickel.Mirrors-you can Google Tollen's Reagent to learn all about this process.reventing Silver Nitrate stains on your skin. Here is a neat trick-Do what I do-Rocky Patterson. 1 - Dissolve 2 teaspoons of common table salt in 1 Cup of warm water. 2 - Place this Salt solution close by where you will be working with Silver Nitrate solutions.

Silver Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal. Silver metal is used in many premodern monetary systems in bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal.

- Mixtures of metals, called alloys, are more commonly used than the pure metal. By alloying, some of the important properties of metals can be improved. 1  Solder, which is used in the electronics industry, is a mixture of tin and lead. Solder, which is used in the electronics industry, is a mixture of tin and lead. 2  One type of solder (63% tin and 37% lead) has a lower melting point but is harder than either of the metals. 3  These properties allow it to be used successfully. 4  An amalgam is an alloy based on mercury.

The Facts on Silver Sterling silver (an alloy of 92 percent silver, blended with copper and other metals) gives a lustrous appearance to coins, jewelry, and silverware. The fact that pure silver is slightly harder than gold, but still very ductile and malleable, makes it a natural choice for dental fillings.

Silver When performance is more important than price, silver is often the material of choice. Silver is rarely found as a native element mineral. When found, it is often associated with quartz, gold, copper, sulfides of other metals, arsenides of other metals and other silver minerals.Unlike gold it is rarely found in significant amounts in placer deposits.ative silver is sometimes found in the oxidized zones above the ores of other metals. It persists there because silver does not readily react with oxygen or water.

Should you Solder it or Braze it? Soldering, on the other hand, involves filler metals with a liquidus of 450°C or below. The issue is further confused by the use of such terms as “silver solder.” This is a misnomer, because silver-based alloys all melt well above 450°C and are therefore clearly brazing filler metals.

The Many Uses of Silver Uses of Silver in Brazing and Soldering. Brazing and soldering make use of silver's high tensile strength and ductility to create joints between two metal pieces. Brazing takes place at temperatures above 600°C, while soldering takes place at temperatures below 600°C.
