Hazardous Chemicals

Danger

There are four hazardous chemicals.

  1. Acid danger
  2. Heat danger
  3. Poison gas danger
  4. Cyanide danger

Chemical is very dangerous. You should protect in every step. You have to wear gloves, mask or protective clothing when you work. When extracting gold finish, you must clean thoroughly with water immediately and learn all kinds of chemicals that you used and how thoroughly protected.

Gold extraction can do several methods. In each method depends on material that you use for extraction. In case, We use electricity; it’s an easy method that you can do it alone. Silt gold extraction is suitable for plated gold such as CPU, Gold in solution, jewelry and so on.

Sample How to extract gold from the Gold Pin connector

The gold extraction from gold pin connector is melting gold pin connector solution form. It’s very is easy and efficient. We can use the process to apply in gold attraction from metal

Observe gold in pin is melt out or not? Loch at the color it become white, that means the gold melt out, from the writer’s experiment can show the chemical, liter can melt some gold most 25 grams, Gold melt depends on the flaws. If the material has more flaws, gold can less melt. This means, the chemical substance is saturated, it cannot melt more gold.

Pour gold pregnant solution from the pin out. You can use Distilled water cleanup pin again. But you must use the least Distilled water because we want the gold pregnant solution to be the richest.

Water that has gold melt will be dirty. You have to filter as shown below Water that has gold melt will be dirty. You have to filter as shown below

 Fill hydrogen peroxide H2O2 40ml per 2000 ml melted gold chemical water. stir it together and wait for 5 minutes.

Fill hydrogen peroxide H2O2 40ml per 2000 ml melted gold chemical water. stir it together and wait for 5 minutes. You have to fill hydrogen peroxide H2O2 in melted gold chemical water to destroy cyanide chemical structure. So, it is not fully element. It cannot melt gold. If we do not fill hydrogen peroxide H2O2 That makes the next step gold piece melted and change into solution.
