Tin sand gold absorption method

Tin sand gold extraction method is an ancient metal extraction technique that can extract metals from ores. This method was widely used in ancient times and is now also used by some researchers to extract metals. This article will introduce the specific steps and precautions of the tin sand gold absorption method.

Step 1: Prepare materials

Prepare materials such as tin sand, charcoal powder, lime, and borax. Tin sand is the main raw material, carbon powder is the reducing agent, lime is the flux, and borax is the catalyst that promotes the reaction.

Step 2: Mix materials

Mix tin sand, carbon powder, lime, and borax evenly in a certain proportion. Generally speaking, the weight of tin sand accounts for about 50% of the total weight of the mixed material.

Step 3: Heating reaction

Put the mixed material into a crucible and heat it in the furnace for reaction. The reaction temperature is generally around 900 ℃. During the heating process, attention should be paid to controlling the speed and temperature of the reaction to avoid excessive reaction or excessive temperature leading to material burning.

Step 4: Cooling and removal

After the reaction is completed, remove the crucible from the furnace and let it cool naturally. After the crucible has completely cooled, open it and remove the reaction products. The reaction products contain metals that can be extracted through further processing.

Precautions:

During the process of mixing materials, attention should be paid to controlling the proportion to avoid affecting the reaction effect.

During the heating process, attention should be paid to controlling the temperature and reaction rate to avoid excessive reaction or material burning caused by excessive temperature.

During the process of removing reaction products, caution should be exercised to avoid safety accidents.

Summary:

The tin sand gold extraction method is an ancient metal extraction technique that can extract metals from ores. This article introduces the specific steps and precautions of the tin sand gold absorption method. Metal can be extracted through this method, but safety and operating regulations need to be taken into account.
