Dont try to do it yourself. Without proper equipment and very dangerous chemicals it is drop dead deadly. If the going rate is only $.65 per pound up there offer to buy it from the yards at $2 a pound and resell it. I personaly wouldnt mess with the chemicals myself not worth getting killed over.
I saw a youtube video of a guy dismantling a microwave. Didn't look all that bad. What exactly would be coming out that has chemicals in it? The last thing he pulled out was copper stuck really good inside of cast aluminum, but with a hammer and a chisell he broke it all up.Quote:

That would make the most sense.Quote:

I think people got confused about his questions because there are no question marks.Quote:

No chems in a microwave. I can answer it in full detail ,every bit of it , that goes same for almost all appliances. I saw a youtube video of a guy with a torch working a CPU that seemed safe. Then of course using acids , and even boiling the acids wile parts are in it looks deadly. First i would have to know how it's done to the same level i know what i work with now. then i would have to factor in all facts . Cost of safety masks , equipment for ventilation. where to buy certain chemicals that i probably wont be aloud to get any way.
Certain building materials for roofs and home's one can only get if they have certification. I have to figure certain acids are the same
Or a really good fume hood!Quote:

Like you said, stick with what you know. The LAST thing you want to do is play with concentrated H2SO4 and HNO3 and whatever other reagents they use in the process.Quote:

If you're a commercial concern - plan on dealing with OSHA, EPA, DOT and a whole slew of other fun guys ...
Here's a simple question that anyone who deals with acids should know - do you add acid to water, or water to acid?
Adding water to the acid gives out a lot of heat, boiling the water and spattering it. Get a faceful and you'd know about it. Adding acid to water gives out the same energy but not the same heat as the water will cool it down.
Easy, I thought you stopped buying out of state? ;)

I have been reading, for me this would take years to figure. Also i see if one was to reclaim say 1.80 grams of gold from CPU's & cards pins . You will need from what i was reading LOTS of pounds. Getting that much computer stuff is not in my realm, So for me it would just be a hobby of sorts. As it stands i have buried my self in motors and so much other that i need to clean. For now going forward with this is a - NOPE - it seems like a investment is also needed. What i want to do is get myself up to 3 to 5 cars per week along with the crazy buried alive mode i am in . The last thing i can do now is set up a laboratory of acids & and glass containers along with sources of heat. getting 1.80 grams of gold seems like allot of work siting in one spot washing and washing till high grade gold it there for the melting ,
$20 bucks in my van for the hunt can net money also that can rival 1.80 grams of gold - lets see 31 grams = 1 ounce @ $1800 and gold is down 1.80 grams is worth less then $200
$5 bucks a LB for computer parts with shipping might be the deal for me .
The only thing that looked interesting to me was a guy on U-TUBE with a CPU and a torch with pliers heating CPU and shaking off the gold into a stainless steal container That's my speed

One last thing There is a energy of luck that lets you find things - Some times I take those finds as omens. Like for me in the beginning of my hunt for metal 2 years ago , i found a small hand held metal detector that still Works. very useful for the down and dirty garbage bag hunch.Well I found a box of sulfuric acid & all sorts of low level electronic testing gauges ,I am not sure but i believe a spectrometer is use to detect or test gold and silver metals some how ?
Actually I had always just been concerned that adding water to acid would cause the acid to splash out, whereas adding acid to water would cause only water to splash. I thought the heat exchange would be the same, but it's been a while since I took chemical thermodynamics. ;)Quote:

There is between 8-11oz of gold in 1 mt (2000) motherboards -lets round off an average motherboard price to 500g -its not far off there anyway. If we take the lower of the 2 values 8oz this equates to a single board containing 0.124g of gold ($6.40 at $1600 poz). However, if you try to reclaim this yourself the chemicals needed are expensive although you can make some of them yourself to lower costs. The cost for refining small amounts will be the same as larger amounts you refine and therefore can make the price of recovery mulitiples of the gold value you obtain. This is not including the days in time spent to refine this when you could be out collecting more.Quote:

Yes X-ray fluorescence spectroscopy is used to accurately detect quantitative analysis of gold. Analytical error is ≤±0.3%. It works by being illuminated by X -Rays. When this happens, energy is absorbed by the material and is re-emitted at a lower energy than the original X-ray and is termed fluorescent radiation. Because the energy of the emitted photon is characteristic of a movement of electrons in a particular element, the resulting fluorescent X-rays can be used to detect the abundances of elements that are present in a sample.
Happy hunting :)
Where can we sell hi-grade boards for $ 6.50 a lb??? I'll bring them a truckload, and I'm sure Easy will send a semi load,,,Quote:
6.50 per Lb for boards is out there ,a final higher value can be obtained.
I think he was figuring that based on what you would get if you sent 1 MT (metric tonne) to a smelter/refiner. Kinda of a average final value of the gold content of a motherboard. I personaly would love to know the breakdown report from a smelted/refined load of different types of boards if anyone in the buisness would be willing to share it for info sake. Im just curious more then anything.
It's the addition of small quantities of water to acid that causes releases heat energy that is enough to cause the water to instantly boil and thus spatter. But if you add a small amount of acid to water it doesnt boil so doesnt spatter (dont hold the container whilst doing this though -it still gets hot enough to burn you) This concept is similar to water into into boiling oil -spatters all over the place. But if you drop boiling oil into water slowly it won't.Quote:
