Hey Procrastinator! I am also new to this great forum. I just want to urge you to try to avoid using "slang words" and abbreviations such as: "oics of biards, yey or ney" as I, even with a translation program, do not understand what "oics of biards" means. In all good intentions and so that you get good answers to your questions. Have seen similar boards before and there seems to be some value, but if they are $5 each, you probably need to get some more input from the pros here on the forum. And to be able to get that, you probably have to take better pictures with better sharpness. This is so that the professionals can see numbers and details on the components, among other things. And feel free to use some kind of reference, for example a rule of thumb or a coin etcetera. Or write the measurements in the text. These boards look consistently high class, but just because they look like that doesn't mean they are. Therefore, you need to take better pictures with more details. And then, for example, I, like many others here on the forum, do not speak English/American as a mother tongue, so try to avoid "slang words". And since the dialogues here on the forum often deal with the use of extremely dangerous acids and chemicals (many of which are precursors to explosive and extremely toxic substances/mixtures), a misspelled letter or number can mean the difference between life and death if it gets really bad. This is "only" my advice to you, all to facilitate your learning of knowledge here on the forum. I almost forgot the most important thing! Before you start mixing acids and wonder why you failed to precipitate any gold, despite a positive stannous test and before you end up with 25 liters of waste: -Study what is here on the forum first, there are several moderators and members who can give you a complete package with links to absolutely necessary basic sources of knowledge. And last but not least, write down a detailed plan of how you intend to implement your processes and post it in a thread here, and you will get the world's best feedback and suggestions on how you can optimize and eventually advanceI have some oics of biards for 5 dollars each board with only little room to negotiate can someone yey or ney
For 5 dollars it will be well worth getting the experience of sorting, doing research, finding and recognizing the valuables on PCB's and how to process different components.I have some oics of biards for 5 dollars each board with only little room to negotiate can someone yey or ney this thankyou for any help. Also these are form airforce base they are mil spec i realize milspec means very little but in this case i think it matters.View attachment 57514View attachment 57515View attachment 57516View attachment 57517
Issuing white ceramics on picture above - you do not need to worry that much about them. As you do not need to crush them before processing. Throw it to the AR as it is and it will be completely fine. Berylium ceram intact, values completely leached out.For 5 dollars it will be well worth getting the experience of sorting, doing research, finding and recognizing the valuables on PCB's and how to process different components.
GO for it! You may get even more off them than 5 dollars in the end in pm's.
Beware of white ceramics (look up beryllium), mercury filled relays.
Think before you do, but don't overdo it....?!
So ask if you are not sure.
Have fun and be safe!
I could not see the first board good enough to make out what is what, so just in general a heads up for hazardous components I know of or have encountered on PCB's.What kind of mercury filled relays you are pointing out ?

Welcome to the forum.Hi I would be interested in them can you post better pictures of the boards?.
so what will you do with the waste contents after PMs are leached?Issuing white ceramics on picture above - you do not need to worry that much about them. As you do not need to crush them before processing. Throw it to the AR as it is and it will be completely fine. Berylium ceram intact, values completely leached out.
Of course, these nice gold plated chips are very appealing to collectors. Bad thing is that they are used. Good thing they are still on the board
What kind of mercury filled relays you are pointing out ?
You treat it according to our dealing with waste here in the forum for the liquids.so what will you do with the waste contents after PMs are leached?
Beryllium oxide is so bad I dont even want to go near it let alone start breaking it up i to dust
No problem. I forgot to say welcomeMy appologies it was before bed and I did not notice my spelling mistakes . It was not slang just my tired eyes.
Seems mostly to deal with disposal of acids.You treat it according to our dealing with waste here in the forum for the liquids.

Solids are disposed through proper disposal channels and regulations where you live.
We for the most part avoid Beryllium like the plague.Seems mostly to deal with disposal of acids.
I hear you. but does anyone with home setups have the ability to manage avoiding contamination from .00001g of Beryllium and does any local means of disposal cater for the safe disposal of such an obscure metal, which is too high on the periodic table to be found with even good handheld xrf testers and is so harmful, a single exposure could kill you now or 30 years down the line? I'd like to know if ppl here are aware of the dangers or even of the presence of this, (in massive quantities by safety standards in the gear they are dealing with
Chill. If you won´t grind it and snort it you will be fine. People wear neckleace or earrings with emeralds and they do not have any in their body - and yet it contains quite a bit of beryllium. There are beryllium bronze tools manufactured and yet people use them and live happy life. The beryllium is caked in the matrix of the ceramic. It is just another "rock" in the wiew of harm potential. Not anything that is espetially harmful.Seems mostly to deal with disposal of acids.

Beryllium is exceptionally carcinogenic when INHALED as dust during metal processing. It is very toxic when some SOLUBLE beryllium compound is ingested or adsorbed through the skin.
Beryllium ceramic isn´t soluble in your body fluids, and if you do not inhale dust from it, it is indiferent, inert material that your body just ignore
Beryllium ions are generated when dissolving any components with beryllium copper. Virtually ALL the common salts of beryllium are HIGHLY soluble.People will always find something to worry excessively about. Those white ceramic IC’s in his photo are not BeO, they’re just alumina ceramic. Beside the safety issues, BeO is also more expensive than alumina so is only used where needed. Due to its better heat transfer capabilities BeO is used for ceramic components that get quite hot during use, such as insulators in microwave tubes and as a substrate for high power output transistors. The form does make a difference also and it’s pretty safe as long as it isn’t broken and can’t be inhaled or pierce the skin. I liken it to barium as an example. Soluble barium compounds are poisonous, but people are routinely given a slurry of insoluble barium sulfate to drink as an radiopaque agent for visualizing the colon on scans. It can’t be absorbed so it passes out of the body without effect.
BerrylliumBeryllium ions are generated when dissolving any components with beryllium copper. Virtually ALL the common salts of beryllium are HIGHLY soluble.
Beryllium hydroxide forms as a gel when hydroxide is added to the acid salt and brought to near neutral pH. It dissolves both in strong acids and strong alkali. It changes form into a rhombic molecular configuration, which precipitates.
But, BeO is a very stable compound. It will only dissolve in concentrated HOT sulfuric acid mixed with ammonium sulfate. Nothing will happen to it in HCl, HNO3, or AR.
Beryllium in nitric tend to precipitate. While the nitric solution grinding metals, it gains pH. At pH 4 Be start converting to hydroxide and at pH 6 all the Be become hydroxide. A nice graph of this phenomenon is available for your inspection at Wikipedia of Beryllium (edited out: "nitrate").Beryllium ions are generated when dissolving any components with beryllium copper.

Why use expensive Nitric when you can use cheap HCl, then filter the Gold out.Berryllium

You may as well tweaking pH by diluting your solution with water. Be(OH)2 is insoluble so it will percipitate, clobbering your precious gold with a white powder. Typically BeCu spring connector are made with 2%-3% Be and the gold coating is less than 1%. So with nitric, in the end you will get much more Be as compared to Au at the bottom of your beaker.
