Help Support Gold Refining Forum:
Welcome to us.
Have you tried to search the forum?
This question pops up almost weekly.
And even if the question itself is simple enough, the answer is not.
It depends on the year/month the brand, and everything else.
Here are some things you should study before diving into the refining pond
We ask our new members to do 3 things.
1. Read C.M. Hokes book on refining jewelers scrap, it gives an easy introduction to the most important chemistry regarding refining.
It is free here on the forum: https://goldrefiningforum.com/phpBB3/viewtopic.php?f=54&t=19798
2. Then read the safety section of the forum: https://goldrefiningforum.com/forums/safety.47/
3. And then read about "Dealing with waste" in the forum: https://goldrefiningforum.com/threads/dealing-with-waste.10539/

In my country, such things are bought individually, the price is something like this:
Large with yellow backing -8,2$
Ceramic with yellow lid and black backing- 12,3$
Here you need to understand that processing such products is not difficult.
hit with a hammer,
and in a glass
but of course there is a margin.
Actually hit it with a hammer a lot! The smaller the pieces the better for the acid to contact any encapsulated pieces. Years ago I used to granulate them and follow up with a ball mill to make it into powder.
many authoritative users, on this forum ,wrote that strong grinding is excessive and only worsens the overall process of extracting gold from ceramics
I originally only passed the ceramics through a granulator before acid, then we realized that finer grinding yielded considerable value over granulation.
That said, the fine powders remaining after aqua regia always yielded values when melted with a copper collector and cryolite. This is a long slow melt that liquefies the ceramic and allows any remaining gold to alloy with a collector. The yield was never high enough to warrant the process for individual lots but was payable for twice annual shipments to a large copper refiner.

I guess if you count the amount of cpu's in the image, I bought them for about 13$/piece which is similar to what you would buy per piece. For the lidded cpu's, isn't it better to remove the lid's with heat instead of smashing them?In my country, such things are bought individually, the price is something like this:
