#0183;#32;Gold can be removed from circuit boards in a variety of ways. It can be scraped off of the boards by hand, which is time consuming, but yields excellent results. The gold can also be removed via a process known as reverse electroplating, where a chemical solution and electricity are used to draw the gold off of the circuit board.
Separate the goldplated metal parts in the circuit boards using a magnet. Some goldplated parts may be inside ceramic components. Put on the goggles and gloves. Place all of the recovered circuit parts in one of the glass containers.
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 new process to remove it uses a mild acid as opposed to harsher chemicals such as cyanide or mercury that are currently used to extract gold. First, printed circuit boards are dissolved in the...
#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.
#0183;#32;The present communication deals with the leaching of gold and silver from the printed circuit boards (PCBs) of waste mobile phones using an effective and less hazardous system,, a thiourea leaching process as an alternative to the conventional and toxic cyanide leaching of gold.
Computer motherboard and other electronic circuit boards can also contain rich gold content made up of goldplated circuit traces, edge fingers, connectors, Integrated Circuits, transistors, amp; memory chips. Extraction of gold by smelting is done with metallic mix gold.
#0183;#32;Gold is used on electronic circuit boards because of its excellent conductive properties and because it doesnt corrode or rust over time. If you still have any of those circuit boards lying around, have a bit of fun and mine them
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.
A printed circuit board contains metals such as copper, tin, silver, and lead along with minute quantities of gold. There are several methods that are used practically to extract gold from a printed circuit board. But before we can start the process we need to
In this technique, the gold extraction is done under very mild conditions while the solution dissolves gold with the fastest rate ever recorded. quot;Gold is stripped out from circuits in about 10...
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
How to Extract Gold From Electronics: In this Instructable, I will show you how to extract gold from computers using products most people have lying around in their homes. The way I extract the gold is relatively straightforward and pretty easy, but the chemicals used are very dangerou
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.
