Scrap gold from electronics

Scrap gold from electronics found in numerous places on ; 1)Mobile phones : PCB, 2)PC Motherboard: IDE connectors, PCI Express slot, PCI, AGP, ISA, and other ports, jumper pins, the processor socket, and DIMM (SIMM on older motherboards) slots 3)Computer parts : Harddisk,CPU processor.All of these connectors are often covered with a fine layer of gold a few microns thick, deposited by flashing or plating.Gold plays an increasingly important role in industrial applications, particularly in electronics, despite its larger use in jewellery and investment products. As the annual statistics show (Gold Survey 2010, GFMS Ltd, London), some 300 Ton or more of gold are used annually in electronic components such as ICs,contacts and circuitry, the latter notably as gold bonding wire.

At the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold into the market. With gold concentrations reaching 300-350 g/t for mobile phone handsets and 200-250 g/t for computer circuit boards, this scrap is an ‘urban mine’ that is significantly richer in gold than the sources of the primary ores today. 'Urban Mine or Urban Mining' so people call it, this is a business about recycling precious metals gold and silver from electronic waste/e-waste,...and GOLD and SILVER results obtained so amazing, kilograms of gold and silver produced from electronic waste such as computers, cellular phones, SIM Card .. Etc.

In Japan,Eco-System.Co produce gold bars weighing 199.58 - 299.37 KG per month with a value of money earned between U.S. $ 5.9 million - U.S. $ 8.8 Million Dollars from e-waste recycle. This amount is certainly not with silver is also produced.

Scrap Gold | Value Scrap Gold

Scrap gold is still a high value gold,what is scrap gold?Scrap Gold is the term given for the process of recycle broken old jewellery, coins and other items that are no longer wanted..this is term "Scrap Gold". Recycling gold has become a large industry, driven by the surge in the price of gold and the current global economic climate. Selling gold jewellery has enabled people to liquidate their assets into cash, a more usable currency in modern life.If we have any scrap gold, we can sell it, but for how much? Gold prices tend to rise when the economy is flat or when there are worries about war or inflation.

What about karat of gold.This is a simple formula can we use to estimate karat gold :  

• 9 K/karat gold is 9/24 = 0.375; 37.5% pure gold  
• 10 K/karat gold is 10/24= 0.417; 41.7% pure gold
• 12 K/karat gold is 12/24= 0.500; 50% pure gold  
• 14 K/karat gold is 14/24= 0.583; 58.3% pure gold
• 18 K/karat gold is 18/24= 0.750; 75% pure gold  
• 22 K/karat gold is 22/24= 0.917; 91.7% pure gold
• 24 K/karat gold is 24/24= 1.00; 100% pure gold  

Scrap gold into its various karat fineness (namely, 10K, 14K or 18k). You may need a magnifying glass to see the number inscribed on the piece. If not, you may need to have the gold tested by a reputable dealer. There's also the possibility that some of the gold is actually just gold-plated, which a dealer would determine with certainty by using a chemical test.

Scrap Gold from Computers

Scrap gold from computers can find from parts of CPU Computers and motherboards. In Japan,Eco-System.Co produce gold bars weighing 199.58 - 299.37 KG per month with a value of money earned between U.S. $ 5.9 million - U.S. $ 8.8 Million Dollars from e-waste (computers,mobilephone..etc) recycle. And this list potential value precious metal (gold,silver..etc) can find from Computers :

Scrap gold from motherboards

Scrap gold from motherboards found in numerous places on a motherboard: IDE connectors, PCI Express slot, PCI, AGP, ISA, and other ports, jumper pins, the processor socket, and DIMM (SIMM on older motherboards) slots.All of these connectors are often covered with a fine layer of gold a few microns thick, deposited by flashing or plating.

With the price of gold being at an all time high, there are now numerous companies who are recycle the infinitesimally small amounts of gold. Most of the gold is found in the motherboards.Here’s a process to recycle scrap gold from motherboards..how to refine gold from MOTHERBOARDS

Scrap gold, silver, platinum from an airplanes

Do yo know if commercial airplanes and U.S military airplanes give back to "graveyards" in the U.S. Southwest contain many thousands of dollars worth of gold, silver and platinum and are significant part of their scrap values....??

"Precious metals are used in airplanes, especially in engines, and when a plane is scrapped, the metals are recovered for their value and recycled," says Terry Hanlon, president of Dillon Gage Metals in Dallas. Gold is useful as a conductor and lubricator, he adds.

Up to 80% part of an airplane can be recycled, and precious metals can provide half of a plane's recycling value. When engines are scrapped or rebuilt, between $6,000 and $18,000 worth of precious metals can be recovered through leaching and radioactive processes. That's no small change considering that gold prices climbed this year, and lots of planes are scrapped in periods of economic weakness and when new models are built.

According to the U.S. Defense Logistics Agency, gold is used in aeronautical circuitry for relays, transistors, diodes and contact points, while silver is employed in electronic parts and welding and brazing wire. Platinum family metals are utilized in aircraft spark plugs and electronics.

Gold is a dependable conductor and connector in aeronautical circuitry. The yellow metal helps plane parts hold up well, reducing maintenance and repair costs. Thin films of it between moving parts serve as lubricants. Gold molecules pass one another under friction, creating lubricant action. The metal's malleability allows it to be processed into a thin film that can coat and protect moving parts.

And because of gold's reflective qualities, many airplane parts are fitted with gold-coated, polyester film to reflect infrared radiation and stabilize temperatures on board. Otherwise, those dark-looking parts of an aircraft would absorb a tremendous amount of heat. Gold is also used in space suits. A thin coating is applied to suits worn by astronauts to protect them from radiation and deflect burning sunlight.

Because gold is expensive, it's only used when cheaper substitutes won't do. But considering the number of lives at risk in air and space travel, and the billions of dollars spent on it, precious metals are worth it.
