To distinguish the gold found in mobile and other electronics, we can easily be at home from the electronics. What do we need? How much?

To extract gold from electronics, you will need the following materials:

1. Safety equipment: Gloves, goggles, and a mask to protect yourself from harmful chemicals and fumes.
2. Hydrochloric acid: Used to dissolve base metals and other impurities, leaving behind the gold.
3. Nitric acid: Used to dissolve any remaining base metals and impurities.
4. Aqua regia: A mixture of nitric acid and hydrochloric acid used to dissolve gold.
5. Sodium metabisulfite: Used to precipitate the gold from the solution.
6. Glass containers: To hold and mix the chemicals.
7. Filter paper: To separate the gold from the solution.
8. Heat source: To speed up the chemical reactions.

The amount of materials needed will depend on the quantity of electronics you are processing and the amount of gold you are trying to extract. It is important to follow proper safety procedures and guidelines when working with these chemicals. It is recommended to start with small batches and gradually increase the quantity as you gain experience.

Materials Required to Distinguish Gold from Electronics:

Quantity | Material
---|---|
1 | Reversing screwdriver set
1 | Soldering iron
1 | Solder wick
1 | Solder flux
1 | Magnifying glass
Nitrile gloves | As needed
Safety goggles | As needed

Steps:

1. Disassemble the electronic device: Use the screwdriver to carefully disassemble the device and expose the circuit board. Wear gloves and safety goggles for protection.
2. Identify potentially gold-bearing components: Look for small, rectangular or square chips or plates with a metallic sheen. These are typically capacitors or resistors that may contain gold.
3. Remove the components: Use the soldering iron, solder wick, and solder flux to remove the potential gold-bearing components from the circuit board.
4. Inspect the components under a magnifying glass: Examine the components closely for any visible gold. Genuine gold will typically have a lustrous, yellow-gold color.
5. Perform a scratch test: Use a sharp object, such as a needle, to gently scratch the surface of the potential gold component. Real gold is soft and will leave a visible scratch.

Note:

- The amount of gold found in electronics varies depending on the type of device and its age.
- Some electronic components, such as gold-plated connectors, may have a thin layer of gold on the surface, which is not valuable.
- It is recommended to take extreme caution when handling electronic components and use proper safety equipment.
