Introduction

This tutorial provides a comprehensive guide on how to extract gold from various electronic components and materials, based on techniques discussed in the video "สกัดทองจาก CPU คอมพิวเตอร์." Whether you are interested in learning for personal knowledge or considering gold extraction as a service, this guide will walk you through the essential steps and methods.

Step 1: Gather Necessary Materials

Before starting the extraction process, ensure you have all the required materials. This includes:

• Safety gear: gloves, goggles, and a mask
• Tools: soldering iron, pliers, and a small hammer
• Chemicals: hydrochloric acid (HCl) and nitric acid (HNO3) for gold extraction
• Containers: glass or plastic containers that can withstand acids

Step 2: Identify Gold Sources

You can extract gold from various sources, including:

• CPU chips
• Integrated circuits (IC)
• Gold-plated jewelry
• Electronic devices (e.g., watches, pens, eyeglasses)

Make sure to only work with components that contain gold or are gold-plated.

Step 3: Disassemble Components

Carefully disassemble the electronic components to access the gold. Follow these steps:

1. Use the soldering iron to heat and remove any solder holding the components together.
2. Gently pry open the casing to expose the internal parts.
3. Use pliers to detach any gold-plated pieces.

Step 4: Prepare the Gold for Extraction

Once you have collected the gold-bearing materials:

• Clean the pieces to remove any dirt or contaminants.
• Cut or break down larger components into smaller pieces to increase surface area for chemical reaction.

Step 5: Chemical Processing

This step involves using acids to extract gold from the materials:

1. Mix hydrochloric acid and nitric acid in a glass container. Use a ratio of 3:1 (HCl:HNO3).
2. Carefully add the gold pieces to the acid solution. Note: This should be done in a well-ventilated area and with appropriate safety precautions.
3. Allow the solution to sit and react. Gold will dissolve in the solution, leaving impurities behind.

Step 6: Precipitate and Collect Gold

After the reaction is complete:

1. Filter the solution to separate the dissolved gold from the remaining impurities.
2. Use a reducing agent (like sodium metabisulfite) to precipitate the gold from the solution.
3. Collect the gold particles and rinse them with water.

Step 7: Refining the Gold

To refine the extracted gold further:

• Heat the collected gold in a crucible until it melts.
• Pour the molten gold into a mold to form bars or other shapes.

Conclusion

Extracting gold from electronic components can be an intriguing and potentially profitable endeavor. By following these steps, you can safely and effectively extract gold from CPUs and other sources. Remember to always prioritize safety by using protective equipment and handling chemicals with care.
