🔍The experiment aims to extract gold from cell phone SIM cards using chemical methods.
💰The yield of gold foils from the process is relatively small.
⚗️The chemicals used include hydrochloric acid, hydrogen peroxide, and sodium hydroxide.
🔥Incineration is employed to burn off remaining materials and leave behind the gold.
🧪The experiment demonstrates a potential method for extracting gold from electronic waste.
What are the materials needed for this experiment?
—The materials needed include cell phone SIM cards, hydrochloric acid, hydrogen peroxide, sodium hydroxide, and a heat source for incineration.
How long does the extraction process take?
—The extraction process can take several days, including the use of chemicals and incineration. Each step requires time for reaction and settling.
Is the yield of gold significant?
—The yield of gold foils from SIM cards is relatively small. This experiment mainly demonstrates the extraction process rather than large-scale gold recovery.
Can this method be applied to other electronic waste?
—While this experiment focuses on SIM cards, similar methods can be applied to other electronic waste containing gold components.
What precautions should be taken when working with chemicals?
—When working with chemicals like hydrochloric acid and hydrogen peroxide, it is important to wear protective clothing, work in a well-ventilated area, and follow proper safety guidelines.
