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 advance
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.
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.
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.
My appologies it was before bed and I did not notice my spelling mistakes . It was not slang just my tired eyes.Hey Procrastinator! I am also new to this great forum.

Welcome to the forum.
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.
Seems mostly to deal with disposal of acids.
We for the most part avoid Beryllium like the plague.
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.

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.

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