Recycling gold from scrap PC boards (2003) I am electrochemical engineer, with years of electroplating experience. A friend of mine wants to recycle gold from PC boards contacts. He has some 100 kg, or so. I would like to help him and set up the process for him.
Not all electronics contain gold. Central processing units (CPUs), pins, and different kinds of circuit boards are all items that may contain gold, with circuit boards being particularly desirable for
Video in Hindi This video is an introduction of gold recovery business from computer scrap and other electronic circuit boards. This video is in Hindi language only. it is made especially for HindiUrdu speaking people.
The term scrap gold recovery refers to the process of extracting gold from old circuit boards, computer chips, computer parts and connectors. Depending on your source of the aforementioned this can be a very affordable way for you to obtain gold.
Steel, copper, zinc, aluminum, brass and other metals make up a significant amount of these items and should be recovered to maximize your profit. Stripped circuit boards have some gold but not enough to recover manually. These can be sold to recyclers who specialize in electronics recovery.
There's always been tiny traces of gold (some as thinner than human hair) on the circuit boards. Just rip amp;39;em and melt amp;39;em for a gold nugget. Screw the stock market, screw cash monies, Iamp;39;m putting everything I have in gold.
Aug 13, 20140183;32;Back in the 70's I extracted the gold, copper and solder from from about a 100Kg of salvaged circuit boards. Even with the thicker gold used in those days I didn't get enough total return to cover the total cost of the processing.
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.
Gold and other precious metals are used in electronic circuits. So, gold recovery from computer parts is a profitable business. We provide training for it. It is a very big business all over the world. You can easily make money from it. We get these metals not only from computer scrap, but from other kinds of electronic scrap also.

The method of gold recovery known as CBX involves dissolving the nongold material of a circuit board with a strong acid, such as hydrochloric acid (HCl). It is only suitable for recovering gold from the edges of connectors, or quot;fingers,quot; of the board and much of the gold is lost during recovery.
Check the boards to make sure all the gold has been removed and dissolved into the aqua regia acid. Remove the basket from the acid, taking care not to drip acid anywhere. The aqua regia is not used up yet, so you can use the same acid to dissolve the gold off more boards.

(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.
Place the goldplated parts of the circuit board into a container. Add two parts hydrochloric acid and one part hydrogen peroxide, which makes a weak 3 percent concentration. Leave the parts soaking for a week, stirring occasionally. The solution darkens, and the gold flakes off. Pass the liquid
Leave a small section of circuit board attached to the pins to avoid losing any gold from them. Step Sort the remaining scrap into piles for later recovery of lesser metals and smaller amounts of precious metals.
100 Gold Plated Scrap Circuit Boards for Gold Recovery. Each lot weighs at least 150 grams and will contain 100 or more boards.
AbstractPrinted circuit boards (PCBs) are currently being dumped in landfills or incinerated which is causing a serious environmental harm in the form of toxic gases or leached hazardous compounds. PCBs contain high amounts of precious metals; about 20 wt% copper, 0.04 wt% gold, 0.15 wt% silver, and 0.01 wt% palladium.

Gold Recovery From Circuit Boards circuit boards A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a nonconductive substrate.
Congratulations, you have decided to enter to the amazing world of computer recycling and electronics recycling, recovering gold and precious metals from E waste is one of the most interesting and challenging practice in the recycling Industry.
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.
Printed circuit boards are first placed in a mild acid, which dissolves all of their metal parts. An oily liquid containing the chemical compound is then added, which extracts gold selectively
