I watch this channel a lot. He has a few where he is refining electronic waste. He usually says that is not really worth it due to the time it takes him to do it and small amounts he gets and can get easily lost in the different stages of extraction. Most of the stuff he does is estate sales and melting down that.

I love this guy's channel! It's interesting, unpretentious, and he has such a wealth of chemical and metallurgical knowledge. The reactions and processes he shows are amazing.
