12/4/2017#0183;#32;Fill the plastic tray with water to half of its depth, place the remaining circuit board scrap in it and rinse. Pour this water through the filter to extract any remaining gold flakes. Flush water over the gold flakes to wash them. Pour the methanol through the filter to wash the gold flakes.
#0183;#32;Computer circuit board scrap was first treated with one part concentrated nitric acid and two parts water at 70#176;C for 1 h. This step dissolved the base metals, thereby liberating the chips from the boards.
1/9/2016#0183;#32;Gold is often found on printed circuit boards, particularly under keyboards where its durability is an advantage. According to the UE researchers, about 300 tonnes of the metal are used in

#0183;#32;Gold is in the circuit boards of Bluray, CD, and DVD players, as well as VCRs and Betamax players. Betamax players contain particularly large circuit boards, but Betamax players were a shortlived technology and can be hard to find. Examples include: Older media players: Sony Betamax players and VCR brands like JVC, Panasonic, and Sony
#0183;#32;Fast copper extraction from printed circuit boards using supercritical carbon dioxide. The size of the equipment also could be reduced, F. Vegli#242;Study on the influence of various factors in the hydrometallurgical processing of waste printed circuit boards for copper and gold recovery.
Extracting gold from a printed circuit board is definitely possible but the amount of the gold in the PCB has to be evaluated first. The process involves a number of steps which have to be carried out carefully in order to get the desired results. There are some instruments and acids involved in the process. Necessary precautions must be taken before starting the procedure.
#0183;#32;Old laptops and desktops Big old desktop computers are about as useful as doorstops, but they still contain small quantities of gold. Pile them up, call us up, and we can explain how to recycle them profitably. And dont forget that gold can be found on printed circuit boards, modem cards, graphics cards, memory chips and other extras that got stuffed into these old machines.
Subject some circuit boards to an acid treatment to release its materials and this stuff will gather up all the dissolved gold. And after it lets go of that gold, its ready to be used again.

How to recover silver and gold from computer parts, ewaste, chips, CPU, xray films, photographic waste, aqua regia, cyanide solution, circuit boards and RAMS. Recovery methods extract or recycle of precious metal like Palladium, Silver and Gold.
Put the gold fingers and clean circuit boards in the coffee pot, in another container mix two parts muriatic acid and one part hydrogen peroxide and add to the coffee pot until it just covers the gold fingers and wait a week giving it a stir daily. Since I have a week I will move
26/5/2017#0183;#32;Someone with the patience to pull them apart and snip the gold pins off their internal circuit boards could realize a profit. The more you collect, the greater your profit can be. Small appliances Air conditioners, space heaters, toaster ovens and just about any other kind of small appliance you can think of all contain trace amounts of gold.
There''s gold in them thar circuit boards laptops, phones, cameras and other devices use the precious metal to connect components, and it can be extracted relatively simply
Most circuit boards contain all sort of precious metals: Gold, Silver, Palladium and sometimes Platinum. All circuit boards contain base metals: Copper, Nickel, Aluminum, Zinc, Tin, Lead and Iron. As well, small amount of hazardous elements like Beryllium, Barium and others that has to be considered while processing scrap circuit boards.
The method involves placing the circuit boards into mild acid to dissolve all the metal parts. An oily liquid which contains a chemical compound is then added, which only extracts the gold.
