The content is a video transcription where the creator attempts to extract gold from 1,000 old SIM cards. The process involves using aqua regia (a mixture of hydrochloric and nitric acid) to dissolve the gold from the cards, followed by neutralization and precipitation using sodium metabisulfite.
After several steps, the creator ends up with a small amount of gold (0.23 grams) which, according to a gold price calculator, is worth approximately 11 euros. However, considering the cost of the SIM cards (80 euros), acids, and time invested, the process is not profitable.
The creator mentions that the goal of the experiment was not to make a profit but to learn and experiment with extracting gold from waste materials. The video ends with the creator encouraging viewers to suggest other objects that may contain gold, which they can experiment with in the future.
Here are the key facts extracted from the text:
1. The author purchased 10 packages of 100 SIM cards each from a seller in Australia for approximately 148 Australian dollars.
2. The author also collected some mobile SIM cards found near a river that couldn't be returned to their owners.
3. A SIM card is a plastic card with a chip that contains a subscription key, allowing users to identify themselves on a network and access their phone number and other services.
4. There are several models of SIM cards, varying in size, with the largest being the oldest and smaller formats being used in newer devices.
5. The author used aqua regia to extract the gold from the SIM cards.
6. Aqua regia is a mixture of hydrochloric acid and nitric acid, which is dangerous to handle and can cause damage to skin and eyes.
7. The author mixed three parts of hydrochloric acid with one part of nitric acid to create the aqua regia.
8. The author used a mask, glasses, and gloves to protect themselves while handling the aqua regia.
9. The aqua regia was used to dissolve the gold from the SIM cards, and the resulting solution was filtered to separate the gold from the other materials.
10. The gold was then neutralized using sodium metabisulfite and distilled water.
11. The author melted the resulting gold powder to create a solid piece of gold.
12. The author used a gold price calculator to determine the value of the extracted gold, which was approximately 10.88 euros.
13. The author spent around 80 euros on the SIM cards and acids, and invested time in the process, making it not profitable.
14. The author's objective was to experiment and extract gold from waste materials, and they were successful in doing so.
