How to Refine Gold From Electronic Scrap December 12, 2008. People are often amazed to learn how much precious metal is lost whenever they throw away their old electronic devices. Gold, silver, platinum and palladium can all be recovered from circuits and processors of electronics. Of all the precious metals, gold is the one most frequently recovered and refined from electronics.

Metal Basics Silver (Ag) and copper (Cu) are some of the most efficient metals and are often used in electronics. 2. Reactivity: Metals are very reactive, some more than others, but most form compounds with other elements quite easily. Sodium (Na) and potassium (K) are some of the most reactive metals. A metal like iron (Fe) forms iron oxide (Fe 2 O 3), which you know as rust.

Precious metal An initially precious metal that became common is aluminium. While aluminium is the third most abundant element and most abundant metal in the Earth's crust, it was at first found to be exceedingly difficult to extract the metal from its various non-metallic ores.

Rare earths: Battling Chinaâs monopoly after Molycorpâs demise? Second, a number of countries are starting to get down to work and developing rare earths projects aimed at capitalizing the widespread use of these minerals throughout a variety of industries. Fifteen lanthanides and two metals -scandium and yttrium- make up the rare earth metals market. Many of these elements are fundamental to the production of electric motors, nuclear reactors, mobile phones, conventional and electric vehicles, wind turbines, solar panels, and missile guidance systems.

Semiconductor Although some pure elements and many compounds display semiconductor properties, silicon, germanium, and compounds of gallium are the most widely used in electronic devices. Elements near the so-called metalloid staircase, where the metalloids are located on the periodic table, are usually used as semiconductors.he semiconductor materials used in electronic devices are doped under precise conditions to control the concentration and regions of p-and n-type dopants. A single semiconductor crystal can have many p-and n-type regions; the p–n junctions between these regions are responsible for the useful electronic behaviour.

Top 10 Most Expensive Metals in the World Molybdenum as one of the most expensive metals is a Group 6 chemical element with the symbol Mo and atomic number 42. The free element, which is a silvery metal, has the sixth-highestmelting point of any element. It readily forms hard, stable carbides, and for this reason it is often used in high-strength steel alloys.

Group 11 element All Group 11 elements are relatively inert, corrosion-resistant metals. Copper and gold are colored. These elements have low electrical resistivity so they are used for wiring.Copper is the cheapest and most widely used.his had led to most modern coins being made of base metals – copper nickel (around 80:20, silver in color) is popular as are nickel-brass (copper (75), nickel (5) and zinc (20), gold in color), manganese-brass (copper, zinc, manganese, and nickel), bronze, or simple plated steel.

Semiconductor Materials Semiconductor materials form the foundation of most modern electronics, including radio, computers, and telephones. Devices can use transistors, solar cells, diodes, silicon-controlled rectifiers, and digital and analog integrated circuits. SRI’s significant advances in semiconductor materials include systems for uniform illumination of large area, high-power semiconductor switches. We also use fluidized-bed Chemical Vapor Deposition (CVD) for high-rate growth of solar cell silicon.

The Metal Profile for Molybdenum High purity molybdenum metal is used in a range of applications from powder coatings to solar cells and flat panel display coating. About 10-15% of molybdenum extracted does not end-up in metal products, but is used in chemicals, most often in catalysts for petroleum refineries.

Metal The best-known precious metals are gold and silver. While both have industrial uses, they are better known for their uses in art, jewelry, and coinage. Other precious metals include the platinum group metals: ruthenium, rhodium, palladium, osmium, iridium, and platinum, of which platinum is the most widely traded.strophysicists use the term metal to collectively describe all elements other than hydrogen and helium. Thus, the metallicity of an object is the proportion of its matter made up of chemical elements other than hydrogen and helium.

INDICATION OF GOLD CONTENT Gold is extremely valuable and probably the most sought after of all the valuable metals found on earth. All things of the physical universe which can be sensed by man are made up of one or more chemical elements. An “element” is a basic simple substance which cannot be further broken down by chemical means.

How much Gold is in a Computer? $9 worth We take apart an old desktop computer to show what is valuable. EScrap such as whole computers or individual components from computers contain gold, palladium and other precious materials. Computer circuit boards have gold and other precious metal traces in densities comparable to mined ore. There is enough valuable material to make refinement profitable on even a moderate scale.
