A precious metal refiner from Guangdong province in southern China has gone viral after demonstrating how he recovered 191.73 grams of gold worth more than 210,000 yuan (over US$30,000) from discarded SIM cards and mixed electronic waste, drawing millions of views and prompting safety warnings from chemical experts.
The man, who operates a social media account under the name “Qiao the Hakka Gold Refiner,” posted the video on January 20 on Chinese social media. It quickly accumulated more than five million views, according to the South China Morning Post.
What the Viral Video Shows
In the footage, Qiao submerges piles of used SIM cards and telecommunications chip waste into chemical barrels, then carries out a series of controlled reactions, including corrosion, displacement, and high-temperature heating, before filtering the material to reveal refined gold.
The process is visually striking. The final frame shows a small but unmistakable pile of recovered gold, which many viewers found difficult to believe originated from everyday discarded electronics.
The gold extraction process involves strong acids, chemical displacement, and high-temperature heating, and requires professional training and controlled facilities.
Social media users were quick to react. Comments ranged from amazement, “Ten years of working is not as good as one year of collecting scrap,” to disbelief that a common item like a SIM card could contain precious metal at all.
Clarification: It Was Not Just SIM Cards
As the video spread, a significant misunderstanding emerged. Many viewers believed the gold had been recovered solely from SIM cards. Qiao later addressed this directly.
Speaking to the Xiaoxiang Morning Post, he clarified that the gold came from processing nearly two tonnes of mixed scrap, specifically gold-plated chip waste from the telecommunications electronics industry, not from ordinary consumer SIM cards alone.
“The purpose of this video was to educate people about the recycling value of electronic waste, not to encourage unsafe or illegal behavior.”
The distinction is important. According to chemical analysts cited in coverage, a single standard SIM card contains approximately 0.47 milligrams of gold, meaning it would take roughly 400,000 cards to extract 191 grams. Industrial-grade telecom chip scrap, however, carries significantly higher gold concentrations.
Why Electronics Contain Gold
Gold is used in electronic components because it conducts electricity efficiently and does not corrode or oxidize over time. It is commonly found in thin layers on contact points, circuit connections, and chip terminals in SIM cards, bank cards, identity documents, circuit boards, and various processor chips.
While the quantity per unit is extremely small, large volumes of electronic scrap can collectively contain economically recoverable amounts of gold, silver, palladium, and other precious metals.
This reality has driven growing interest in the technology sector around formal e-waste recycling as a resource recovery strategy particularly as global e-waste volumes increase year on year.
Experts Warn of Serious Chemical Hazards
The viral attention triggered immediate concern from chemical safety professionals. The gold extraction method shown involves highly corrosive substances, including strong acids such as hydrochloric and nitric acid, which form aqua regia a mixture capable of dissolving gold.
Experts cautioned that amateur attempts to replicate the process carry severe risks, including inhalation of toxic fumes, chemical burns, long-term respiratory damage, and environmental contamination from improper acid waste disposal.
Local Chinese authorities and environmental agencies urged the public not to attempt do-it-yourself gold extraction. They emphasized that licensed electronic waste recycling facilities operate under strict regulatory frameworks designed to manage these hazards safely and minimize environmental impact.
It is also worth noting that extracting metals from e-waste without proper licensing is illegal in China, India, and many other jurisdictions. Violations can result in significant penalties.
The Broader E-Waste Challenge
The incident has brought renewed attention to the global electronic waste crisis. Hundreds of millions of old smartphones, SIM cards, laptops, and household electronics are discarded every year, despite containing recoverable precious and rare earth metals.
China has introduced multiple national policies encouraging responsible e-waste recycling through licensed channels. Analysts say properly regulated recycling reduces pollution, conserves natural mineral resources, and contributes to a growing green economy.
This connects to a broader pattern of China’s expanding role in technology manufacturing and recycling, as well as growing global pressure on electronics companies to build more sustainable supply chains.
For those interested in how technology intersects with environmental responsibility, the case of Qiao serves as a clear illustration: what is possible in a professional, licensed setting can be extremely dangerous and illegal when attempted without proper controls.
The video remains available on Chinese social media, where it continues to draw debate about the value hidden in everyday discarded devices and the limits of viral knowledge sharing when the safety context is stripped away.
