SIM卡炼金火了，真能在家炼黄金？别被视频骗了

Group 1 - A man claimed to extract 191 grams of gold from over 170 kilograms of SIM card waste, which quickly gained attention online, but later clarified that the material used was industrial waste, not ordinary SIM cards [1] - A standard SIM card contains less than 0.02 grams of gold, and extracting gold from one ton of cards would yield only about 20 grams, requiring professional recycling facilities for safe processing [2] - The incident led to a surge in videos showcasing the extraction of gold from electronic waste, but many failed to mention the legal requirements and dangers involved in such processes [4] Group 2 - China generates over 14 million tons of electronic waste annually, containing approximately 300 tons of gold, surpassing the annual output of domestic gold mines, yet over 90% of this waste is processed by informal methods that harm the environment [5] - Educational professionals expressed concern over the simplification of complex industrial processes in popular videos, warning that such portrayals could encourage dangerous DIY attempts among viewers [7] - Popular videos often focus on the shiny gold output while neglecting the hazardous materials and safety equipment necessary for proper gold extraction, misleading the audience about the complexity of the process [8]
