Recently, a claim that ‘a mobile phone SIM card contains 0.02 grams of gold’ has been circulating online. After verification by multiple sources, this information has been confirmed as false. While SIM cards do contain trace amounts of gold, the quantity is extremely small—typically only about 0.02 milligrams (0.00002 grams) per card, not 0.02 grams. This discrepancy likely stems from a unit misunderstanding or exaggerated description.The gold in SIM cards is primarily used for plating the chip and metal contacts to enhance conductivity and prevent corrosion. However, due to the minuscule amount of gold per card, the cost of recovery far exceeds the value of the gold itself, making recycling impractical. Such rumors may originate from oversimplified or misleading interpretations of precious metal recovery from electronic waste.Experts advise the public to approach such information rationally and avoid being misled by inaccurate content. Those interested in precious metals in electronic devices should focus on formal e-waste recycling industries rather than attempting to disassemble small electronics themselves.
近日，网络流传“手机SIM卡含有0.02克黄金”的说法，经多方查证，该信息为不实传言。SIM卡内部确实含有微量黄金，但其含量极低，通常每张卡仅含约0.02毫克（即0.00002克）黄金，而非0.02克。这一差异是由于单位误解或夸大描述导致的。SIM卡中的黄金主要用于芯片与金属触点的镀层，以提高导电性和防腐蚀性能。然而，由于每张卡的黄金含量微乎其微，回收成本远高于黄金本身价值，因此并不具备实际回收意义。此类传言可能源于对电子废弃物中贵金属回收的过度简化或误导。专家提醒，公众应理性看待此类信息，避免被不实内容误导。若对电子设备中的贵金属感兴趣，可关注正规的电子回收产业，而非自行拆解小型电子产品。
