Pins with Extremely Thick Gold Plating (Massive Yield)

In this video, we dive into the recovery process of 800g of high-grade Soviet-era СНП and РППМ gold-plated pins. These connectors are legendary in the gold recovery community for their exceptional plating thickness, and today we put that reputation to the test. I’ll walk you through each critical stage—from the initial chemical stripping and base metal leaching to the final precipitation and melting of the gold. If you're interested in e-waste recycling, precious metal refining, or the chemistry behind gold recovery, this is exactly what it takes to turn raw industrial scrap into a high-purity gold button. Key stages in this recovery: 00:00 Intro to the Soviet gold-plated pins 02:15 Chemical stripping process 04:30 Filtering and refining the gold mud 06:45 The final melt and 33.1g yield reveal What I used in this video: Nitric Acid & Hydrochloric Acid (Aqua Regia) SMB for precipitation Ceramic crucibles for the final melt Safety Disclaimer: Precious metal refining involves hazardous chemicals and toxic fumes. Always work in a well-ventilated area (like a fume hood) and use proper PPE, including respirators, gloves, and eye protection. Do not attempt this without proper training and equipment.
