The video demonstrates a process to extract gold from damaged computer parts, specifically RAMs. The host collects computer parts, mostly RAMs, which they purchased for Rs. 20,000 (approximately $250 USD). The process involves several steps:
1. Creating a solution using hydrochloric acid and 3% hydrogen peroxide to separate the gold from the plastic.
2. Soaking the computer parts in the solution for 6-7 days.
3. Filtering the solution and collecting the gold particles.
4. Creating Aqua Regia, a mixture of hydrochloric acid and nitric acid, to dissolve the gold particles.
5. Filtering the Aqua Regia solution and collecting the gold particles.
6. Adding sodium meta bisulphite to the solution to separate the gold from the acid.
7. Filtering the solution again and collecting the gold particles.
8. Melting the gold particles using a crucible and borax to create a solid gold ball.
The host notes that the process is not practical or profitable for large-scale gold recovery, as the cost of the process exceeds the value of the extracted gold. However, the video demonstrates the scientific possibility of extracting gold from computer parts using household chemicals and materials.
Here are the key facts from the text:
1. The process of extracting gold from computer parts was attempted.
2. The computer parts used were mostly damaged rams.
3. The parts were bought for Rs. 20,000.
4. A solution was made using Hydrochloric acid and 3% H2O2 to separate the plastic and gold.
5. The solution was left for six to seven days to allow the reaction to take place.
6. The solution was then filtered using filter paper.
7. Aqua Regia was made using Hydrochloric acid and Nitric acid in a 3:1 ratio.
8. The gold was dissolved in the Aqua Regia.
9. Sodium meta bisulphite was added to the solution to separate the gold from the Aqua Regia.
10. The solution was filtered again using filter paper.
11. The gold was melted using a crucible and borax.
12. The gold was shaped into a ball.
13. The total cost of the process was Rs. 14,000, but the value of the extracted gold was not specified.
14. The process of extracting gold from computer parts is not practical on a small scale, but it may be profitable if done on a large scale in a factory.
