Run the actual numbers on "SIM card gold" before you start dissolving things in acid.
A SIM card contains roughly 0.5 to 1 milligram of gold. At today's gold price of ~$4,500 per ounce, one milligram is worth about $0.15. Fifteen cents. Your SIM card's gold is worth less than the electricity it takes to read this tweet.
The video going viral right now is from a Chinese blogger who claimed to refine 191 grams of gold from SIM cards. Worth about $28,000 at current prices. What the video doesn't show: the creator later admitted the process required 2 tons of raw materials, not just SIM cards, and most of the source material was other gold-plated electronic waste that never appeared on camera.
The math on pure SIM card extraction is brutal. At 1 milligram per card, you need roughly 31,000 SIM cards to get a single troy ounce. The chemical process requires aqua regia, a mixture of hydrochloric and nitric acid that produces chlorine gas. One experienced refiner on a gold recovery forum bought 900+ pounds of SIM cards expecting 0.6-0.8 grams per pound. Actual yield: 0.1 grams per pound. He described it as a "big time" loss.
The world produces about 4.5 billion SIM cards per year. If you could magically collect every single one and extract the gold perfectly, the total yield would be roughly 4,500 kilograms. At $4,500/oz, that's about $650 million. Sounds large until you realize that's 0.003% of global gold production value. The entire planet's annual SIM card output contains less gold than a single mid-size mine produces in a year.
The real gold in your SIM card is the copper and nickel underneath. The gold layer exists because gold doesn't oxidize at room temperature, keeping the contacts functional for years. It was never there to store value. It was there to prevent a $0.50 part from corroding and bricking your $1,000 phone.
Every "secret gold source" video follows the same formula: show the shiny output, hide the input costs, skip the chemistry that can hospitalize you.
