Gold recovery from electronic trash is important for sustainable resource management and financial gain. Electronic trash generation has increased due to the quick development of technology and the widespread use of electronic devices in daily life. In trace amounts, integrated circuit (IC) chips, one of the many parts of electronic gadgets, include precious metals such as gold. One way to recover valuable resources from discarded electronics and lessen environmental effects is by extracting gold from computer-integrated circuits (ICs).
A comprehensive overview of the intricate process of extracting gold from computer-integrated circuits will be provided in this tutorial. Each stage requires precision and prudence to succeed, from disassembly to smelting. Even though it could appear to be challenging, the extraction process is appealing since it has the potential to result in both financial gain and environmental benefits. Through the process of extracting gold from electronic waste and so unleashing a valuable resource, we contribute to the preservation of natural resources and the reduction of pollution caused by electronic waste.
Safety Precautions
Safety must be the priority before beginning the process of extracting gold from computer-integrated circuits (ICs). While working with chemicals and electrical components, several risks must be carefully evaluated, and safety protocols must be followed.
First and foremost, emphasizing the significance of maintaining a constant awareness of your surroundings during the extraction process is paramount. To accomplish this, it is necessary to be aware of the potential dangers associated with working with electronic components and chemicals and the measures that need to be taken to mitigate them.
It is of the utmost importance to strictly adhere to a thorough set of safety procedures to ensure the safety of all individuals participating in the extraction process. To protect oneself against exposure to hazardous substances, it is necessary to wear appropriate protective gear, including respirator masks, goggles, and gloves. Working in a location with enough ventilation offers several advantages, including reducing the danger of inhaling toxic substances and guaranteeing adequate airflow throughout the extraction process.
More than that, handling chemicals with extreme caution is essential to prevent accidents or injuries. If it is not handled correctly, sulfuric acid, typically utilized in the extraction process, can cause severe burns and irritation to the respiratory system. Because of this, it is extremely important to be aware of the appropriate disposal methods and to take the necessary safety precautions when working with and storing chemicals.
In conclusion, it is of the utmost importance to thoroughly understand the potential risks and hazards associated with the extraction process to ensure the safety and well-being of everyone involved. It is possible for individuals to create a secure working environment to recover gold from computer integrated circuits (IC) chips by adhering to severe safety rules and putting proper processes into place.
Equipment and Materials
You will need the following tools and supplies to remove gold from computer IC chips successfully:
- Hot Air Gun: You need a hot air gun to take IC chips out of electronic gadgets safely. It gives off enough heat to melt the solder and separate the chips from the circuit boards.
- Glass Containers: During the extraction process, different liquids and parts are kept in glass containers. To keep people safe when working with chemicals, they should be able to handle heat and not react with chemicals.
- Sulfuric Acid (98%): Sulfuric acid is important for removing the black substance with gold wires from the IC chips. For best results, use sulfuric acid that is of good quality and has a concentration of 98%.
- Water: Once the gold wires are removed from the black compound, they are rinsed and cleaned with water. It helps get rid of any impurities or chemical leftovers that are still there.
- Blaster Gas Torch Butane: To get pure gold from gold wires, a Blaster Gas Torch Butane is used to melt them. It gives off the high temperatures needed to melt the gold and separate it from other impurities.
Every piece of equipment has a specific job in the extraction process, from sorting the IC chips to making the gold that was removed better. To ensure the extraction is safe and effective, you should learn how to properly use and hold each tool.
You can get the materials and tools from several places, such as hardware shops, specialty chemical suppliers, and online stores. Before starting the extraction process, it is important to ensure that all the materials and tools meet safety standards and can be used for what they were made for.
Step-by-Step Extraction Process
● Preparation
Before starting the extraction process, you must ensure your area is ready and has all the necessary materials and tools. Create a room with good airflow and enough room to work safely. Wear safety gear like gloves, goggles, and a gas mask to protect yourself from dangers.
● Separation of IC Chips
Carefully heat the electronic device that has the IC chips with a hot air gun. The heat makes the solder less stiff, which lets you remove the IC chips from the circuit boards without hurting them. Be careful not to damage the chips by burning them during this process.
● Disassembly of IC Chips
After taking out the IC chips, split them into the green circuit board and the black substance with gold wires. Carefully remove any extra parts or pieces still on the chips to make the extraction process easier later on.
● Dissolving the Black Compound
Bringing sulfuric acid (98%) to a specific temperature is essential in a glass container. Temperatures should be somewhere in the neighborhood of 90 degrees Celsius. If you want the dark substance containing gold wires to dissolve, put it into the fluid. The fluid should occasionally be stirred to guarantee that the substance is completely dissolved.
● Cleaning the Gold Wires:
Following the removal of the black substance, the gold wires should be thoroughly washed with water to eliminate any dirt or chemicals that may still be present on them. It is important to exercise caution when handling the solution and ensure sufficient airflow to prevent fumes from entering your eyes.
● Separation and Collection
Once the gold wires are clean, pull out any fibers or other junk still on them. Gather the gold wires into a ball to be used in other steps. During this step, be careful not to lose any valuable gold material.
● Smelting the Gold
Heat the gold lines with a butane gas blowtorch to melt them and get pure gold. The torch’s high temperatures melt the gold, which lets it separate from any other impurities that are still there. Keep heating it until the gold is fully melted and free of other materials.
● Refinement and Storage
If you need to, refine the melted gold even more to get it to the amount of purity you want. This could mean using extra cleaning methods or treatments to eliminate any impurities. Once the gold has been refined, it should be kept safely in a marked container or storage facility to avoid getting lost or tainted.
By following these step-by-step directions, you can get pure, refined gold from computer IC chips that can be used in several ways. Safety should always come first during extraction, and waste should be thrown away properly.
Yield and Profitability
Several factors can influence the average yield of gold from computer-integrated circuit chips, including chip size and type. Approximately seven to twelve grams of gold can be extracted from one kilogram of BGA-type integrated circuit chips. Although individual extraction yields can appear to be very low, increasing the scale of the operation might result in large profits over time.
The cumulative output from processing a significant amount of electronic trash can be substantial even though the quantities of gold recovered from each chip are modest. Because of this, there is a significant potential for profit from gold recovery activities carried out on a bigger scale. It is possible for people and enterprises to benefit from the value of precious metals contained within electronic trash while also contributing to efforts to conserve resources and reduce waste. This can be accomplished by efficiently extracting gold from computer IC chips and maximizing recovery rates.
