Gold Recovery: Extracting 24K 🪙 Gold from Laser Diode Scrap

Recovering 5.03g Gold from 47 CPU's ($500 Value Scrap Processors)

Today I'm taking on a major challenge. I have 47 high-grade vintage ceramic CPUs, and I'm going to extract every last bit of precious metal hidden inside them. From the initial processing to the final melting at 1064°C. Watch the full professional refining journey.

After careful chemical refining and processing, the final yield is:
Pure Gold: 5.03 grams
Silver: 3.40 grams
Estimated Value: Nearly $500!

Gold 🪎 Recovery Using Apple Cider Vinegar

In today's video, I demonstrate gold recovery from cellphone flex keypads using a solution made of apple cider vinegar, sea salt, and 3% hydrogen peroxide. It has been confirmed that this method successfully separates gold plating from gold fingers, gold-plated PCBs, and similar materials. The stripped gold can then be refined into pure gold with a small amount of aqua regia. Like white vinegar, apple cider vinegar is highly effective for gold recovery processes. Purchasing 128 ounces or a gallon of apple cider vinegar from Walmart costs only a few bucks, making this an affordable and efficient method.
