How to Recover Gold from Old Mobile Phones | Step by Step Gold Recovery Process

​In this video, I demonstrate the complete chemical refining process to extract gold from 5 kilograms of old cell phone IC chips. Watch the entire journey from chemical leaching, filtering, and neutralizing the aqua regia solution with urea, to precipitating the gold using sodium metabisulfite (SMB). ​You will see how the gold precipitate settles over 12 hours, followed by careful decantation, washing, and the final smelting process using a borax and sodium carbonate flux at 1064°C. ​Watch the video till the end to see the final melting process and find out exactly how many grams of 18k-21k gold button we managed to recover from this batch of e-waste! ​⚠️ Safety Warning: This process involves hazardous chemicals, acids, and high temperatures. Always work in a well-ventilated area or fume hood and wear proper safety gear (gloves, goggles, and respirator).
