2000. A. The amount of gold you will get from 4 tons of circuit boards may not be worth the effort and cost. There are at least two ways to get the gold: (1) cut off the tabs and strip them in cyanide (2) burn the entire collection, smelt the copper and gold out of the ash, then extract the gold from the copper.

Oct 26, 2017· E-waste can often comprise of several hazardous components which can include heavy metals like mercury and lead. Despite this reality, gold, as well as other precious metals, also make up a significant amount of e-waste, and its extraction could have advantageous properties for the gold industry. E-Waste Statistics 2

Gold is the highly efficient conductor that can carry these tiny currents and remain free of corrosion. Electronic components made with gold are highly reliable. Gold is used in connectors, switch and relay contacts, soldered joints, connecting wires and connection strips.

Step. Start by obtaining as many scrap electronics components to reclaim gold from. Generally speaking, older electronics work better because enhanced manufacturing processes use less gold than older electronics, so an old 386 or 486 computer, for example, contains more gold .

Gold is an ancient staple of jewelry and ornament. Platinum, too, is a perfect setting for diamonds and other precious gems. The two metals also have many industrial uses, and are common components in many electronics. Gold and platinum can be recovered from computers, catalytic converters, plated materials and many other common items.

Apr 24, 2017· Gold is a precious, conductive, and pliable metal that retains a stable value better than many commodities. Its chemical properties make it useful for the manufacture of computers parts, electronics, jewelry and dental work. Some people find it profitable to attempt to extract the gold from these scraps, then refine and sell it.

nano-tech Security IC's mounted on a flexi-PCB that is gold plated on both sides with thick layer high Karat gold (in most cases). The chip parts of the plastic cards are easily peeled off and processed, and should yield very high amount of gold – somewhere between 6 .

Uses of Gold in Electronics. The most important industrial use of gold is in the manufacture of electronics.
