The viral "SIM card alchemy" video is actually exaggerated.

Some self-media outlets claim that each SIM card contains 0.02 grams of gold, while each credit card chip can extract 0.2 grams of gold. Does this mean that the SIM card and bank card we use regularly really have such a "gold content"? We interviewed some experts on this matter. The experts' answer was: Yes, SIM cards can indeed extract gold, but the content is very low, and only professional institutions can operate it. Faced with the public outcry, the person involved later clarified that he extracted gold using 2 tons of raw materials, did not show all of it in the video, and it was not just SIM cards or credit card chips, but a collection of electronic chip waste containing gold plating. Mr. Lin, who has been engaged in the precious metal recycling industry for a long time, told reporters that the precious metal recycling industry is already very mature, from SIM cards to keyboards to various electronic devices, there are usually gold-plated coatings. However, some self-media reports have errors in common sense. Compared to the claim that a SIM card has 0.02 grams of gold, in fact, the now commonly used Nano-SIM card can extract 0.02 milligrams of gold, which is already good, and this is a difference of 1000 times from what is said online.
