🛠Old computer parts, like video cards and RAM, contain valuable gold worth extracting.
📈Dissolving base metals leaves gold foils that can be separated.
🧩Using hydrochloric acid and hydrogen peroxide creates a chemical reaction that dissolves base metals.
✅Filtering the solution removes impurities and leaves a gold-bearing solution.
🤑Adding sodium metabisulfite precipitates gold out of the solution as a metallic powder.
What computer parts can be used to extract gold?
—Old computer parts like video cards, RAM, and motherboard connections contain gold that can be extracted.
What chemicals are required to extract gold from computer parts?
—Hydrochloric acid and hydrogen peroxide are used to dissolve base metals and separate gold foils.
How do you separate gold foils from dissolved base metals?
—By stacking the parts, dissolving base metals with acid, and allowing gold foils to fall away.
What is the purpose of filtering the solution?
—Filtering removes impurities, leaving a gold-bearing solution that can be further processed.
How is gold precipitated out of the solution?
—Adding sodium metabisulfite causes a chemical reaction that precipitates gold as a metallic powder.
