Modern-Day Alchemy: Chinese Refiner Extracts $30,000 Worth of Gold from 2 Tonnes of E-Waste. -

In a viral display of recycling innovation, a man from Guangdong, China, known as “Qiao the Hakka Gold Refiner,” has successfully extracted 191.73 grams of gold from scrap SIM cards and electronic waste. This impressive haul is valued at approximately US$30,000 (nearly 200,000 yuan), showcasing the high value hidden within modern-day electronic scrap.

The Process Behind the “Alchemy”:

The Raw Material: Qiao clarified that the gold did not come from SIM cards alone; he processed nearly two tonnes of scrap, including gold-plated telecom chip waste.
Extraction Technique: The process involves immersing the waste in chemical barrels to facilitate corrosion, displacement, and heating. This produces “gold mud,” which is then filtered and smelted at extreme temperatures into a solid ingot.
Why Gold?: SIM cards and bank chips use a thin layer of gold on contact pins to enhance conductivity and ensure corrosion resistance.

A Stern Warning to Amateurs: While the video has triggered a “buying frenzy” for old SIM cards online, Qiao and industry experts have issued a deadly warning:

Toxic Chemicals: The method typically uses Aqua Regia (a highly corrosive mixture of nitric and hydrochloric acids).
Lethal Risks: One mistake in temperature or pH control can release toxic gases or trigger explosive reactions.
Legal Consequences: In China, old SIM cards are classified as hazardous waste. Unauthorized refining can lead to fines of up to 500,000 yuan and multi-year imprisonment for environmental pollution.
