The method of extracting gold from Xisha

Gold is one of the oldest precious metals in human history, and its preciousness is self-evident. However, the mining and extraction of gold is not an easy task. In this article, we will introduce the method of extracting gold from Xisha, which is a very effective method for extracting gold.

What is the method of extracting gold from Xisha?

The Xisha gold extraction method is a method of separating gold from other impurities. This method uses tin sand as a reducing agent to separate gold from other impurities. Xisha gold refining method is a relatively simple method, which can be carried out at home, but requires some basic chemical knowledge and Laboratory equipment.

Step 1: Prepare Laboratory equipment

You need to prepare some Laboratory equipment before the experiment of extracting gold from tin sand. These devices include:

1. Basic laboratory instruments such as beakers, test tubes and Glass rod.

Platinum and tin sand can be purchased at chemical reagent stores or online.

3. Sodium hydroxide, hydrochloric acid and nitric acid are chemical reagents, which can be purchased in chemical reagent stores or online.

4. Flame or hot plate, used to heat laboratory equipment.

Step 2: Prepare the gold sample

Before conducting the experiment of extracting gold from tin sand, you need to prepare some gold samples. These samples can be gold jewelry or coins, etc. Firstly, you need to put the gold sample into a beaker and add enough hydrochloric acid and nitric acid. This will dissolve other impurities, leaving only gold.

Step 3: Add tin sand

Once you have prepared the gold sample, you can start adding tin sand. Add the tin sand into the beaker, and then stir with a Glass rod until the tin sand is completely dissolved. This will produce a reducing agent that can separate gold from other impurities.

Step 4: Heat the mixture

Once you have added the solder paste, you can start heating the mixture. Place the beaker on a flame or hot plate and heat the mixture. As the temperature increases, the tin sand will begin to restore gold. This will cause the gold to separate from other impurities and form a solid metal ball at the bottom of the beaker.

Step 5: Separating Gold

Once you have completed the heating process, you can separate the gold. Remove the beaker from the flame or hot plate and place it on a cooling rack. Once the beaker has cooled, you can remove the golden ball from the beaker. This will be a pure golden ball that can be used to make jewelry or other items.

conclusion

The Xisha gold extraction method is a very effective method for extracting gold. It can be done at home, but requires some basic chemical knowledge and Laboratory equipment. If you want to try the method of extracting gold from tin sand, please ensure that you follow all safety guidelines and make sure you are fully prepared before conducting the experiment.
