Urban gold prospecting

[Ohiogoldfever]

Weathers cold, the creek is colder.

Anyone else do any urban prospecting to pass the time?

[Ohiogoldfever]

Nobody! Holy crap. Beats waiting out the cold weather or god forbid buying gold in bags of dirt. This controller looks like it may yield 10-15 grams.

Plus who doesn’t like taking things apart that you don’t have to put back together! Haha.

i have been collecting for about 15 years and have a full 5 gallon bucket.
for some reason people like to take their old electronics out to the desert,
shoot it and leave it out there. i used to shoot alot and started picking up the gold parts and chips.
the old penteum pro chips had a lot of gold in them.
many years ago i refined with aqua regia a little and made this .999 fine button.
260 grains.
if your doing it for money, just sell the parts at an auction site as scrap gold.
if you are tring to recover the gold i hope you have a lab with a hood vent, scrubber and a way to
deal with the toxic waste.
ar is no joke, one one whiff and your lungs will be trash.
sell it as scrap, its a lot of work and Hassle. really think about it.
oh and also you will probably end up on a government watch list if you start googling how to make the
chemicals you need for refining. HNO3 can make some interesting things.

Try the Iodine leaching method,no acids and it does work.Check out Moosescrappers videos for some methods that only use Muriatic acid,they work too.Lots of ways to do this without the Nitric,may be a little slower but lots safer too.I don,t really care if I,m on a watch list,probably on some already,only hazard to any Govt.investigators is they might die of boredom looking at my life!

I agree, AR is some nasty stuff. I’m mostly collecting stuff at this point but very well may set up to toll refine as I know a guy local to me.

It’s a hobby gig just like panning the creek. Easier to find gold in electronics than it is in the creek. At least here in Ohio.

Trick is finding the right scrap.

The BEST gold I ever got was from pre-1966 telephone equipment. back then they used 24 K gold and it went on heavy !! The old phone relay's were the best ! Big globs of gold for contacts. I also got a lot of silver from wore out hi-power / high voltage switch gear. That was a once in a life time find !

[Ohiogoldfever]

Gotta love the old stuff! When gold was cheap! Bigger the glob, the betta the job.

Naval electronics are heavy on the gold. Just be careful with scrapping the power transistors, as they use amalgam to hold the silicon die down.

I go after gold plate on ceramics with HCl and bleach. Some of that plating can be thick. I have a bunch to do, but would rather save my P100 acid filters for Covid right now!

[Ohiogoldfever]

I’ll have to do some digging on the naval electronics. I’m pretty land locked so that’s a factor.

Anyone know a place to look for old testing equipment? Oscilloscopes or other vintage stuff? eBay is pretty hit or miss unfortunately.

On another note. Here’s 450 grams of heavily plated pins.

I'll see your 450g and raise ya This was part of 51 lbs of material I recently sent in and comes in at about 2g a pound. Take's a lot of work and time but it pays well.

[Ohiogoldfever]

Hot damn! Nice pile!

You say send in? You send out to a refiner? I’m curious to know who you’d use and what toll costs are.

[DDancer]

Yes I use a refiner because I'm not going to get involved in all the equipment involved, or chem's, but I have to get a lot of material up before it can be accepted. Minimum of 40 lbs of clean high grade material (my material is mostly milspec), 200 lbs if your doing circuit board stuff to be profitable. Cost's varies and is taken out of the settlement~ Assay, processing, environmental, office fee's~ then there's their cut for metals, the refiner I'm using pays for and keeps this percentage on the following metals : AU 10%, AG 20%, PD 25% and CU 25%. That's pretty typical. I'm not going to say who I use because I feel its a good idea for anyone looking to do this to do the research. Its eye opening and good to know info. My out of pocket cost has been shipping but with larger quantities I could get reimbursed.

[Ohiogoldfever]

Thanks for all the info. I surly understand your not wanting to pass along a name. I doubt I’ll be amassing enough to meet the requirements anytime soon anyhow.

I enjoy just pottering away at it. I may set up and refine as I get the time. Looks like a fun new hobby as long as done carefully. I hope to meet up with a local guy to do some hands on learning. He’s got more than a decade in refining so I’m sure I can learn a thing or two.

[DDancer]

I find it a good way to pass time as well as make a buck in the urban mines Have fun.

I’ve done a bit of this using HCl (pool acid) which is cheap and works very well if one is patient.
