I am new to this forum, but I am not accustomed to being insulted and just taking it because I am new. I learned long ago that a man must stand up for himself because few others will stand for you or with you when you allow yourself to be mistreated. Though his knowledge, I'm sure, is very valuable to have had available to me. Our first impressions of each other are not exceptional. I intend, if allowed, to stay here and both learn and hopefully add to this forum whatever I might find isn't included already.



I've been recycling brass, copper, and cardboard for a number of years now. I've decided to stop doing those.
I currently sell odds and ends on eBay along with having my regular job.
I've been collecting ewaste on the side for (like you said) about ten years now. Never sending it to someone, thinking the return might be too low.
Never using Aqua Regia because I'm a long way away from my chemistry days, though I'm still interested in trying, but only with strict protocols.

I've admired this community for years. I am still very new to the processing side of ewaste. All of the videos and web pages on the internet are nothing compared to what is contained here.

Two things you and I have in common, scrapping metal and swimming. Swimming was my life until I went into the Navy.

I think you have plating like your skin its THIN. The only person that was rude insulting or miss treating anyone was you. Sorry your scrap is not what you think but it's not. It's a thinly gold plated a Cu alloy. The only "solid" Au part is the wire attached to the silicon wafer. IR detectors will be like any other light detecting chip.

The amount of solid gold components in high end electronics is next to none. Targets, some tubes.

There are some solid Pt parts and that is due to heat resistance and there are solid silver for it's conductivity.

If you want to know the gold value find the surface area in square inches and multiply it by $0.05. That should give you a good idea of what you have.
