استخراج واستخلاص الذهب من الصخور والتراب بأفضل طريقة ( الجزء الثالث )

Introduction

In this tutorial, we will explore the process of extracting gold from rocks and soil, specifically focusing on the second filtration phase, washing the soil, neutralizing the solution, and preparing for smelting. This guide is aimed at helping you understand each step involved in gold extraction, ensuring you can safely and effectively perform the procedure.

Step 1: Conducting the Second Filtration

• Begin by preparing your materials for the second filtration.
• Use a fine mesh filter or cloth to separate the solid materials from the liquid solution.
• Pour the mixture slowly through the filter to ensure all fine particles are captured.

Step 2: Washing the Soil

• Collect the filtered soil in a clean container.
• Rinse the soil thoroughly with water to remove impurities.
• Agitate the soil gently to ensure thorough washing. This helps in retaining the gold particles.
• After washing, let the soil settle for a few minutes and then decant the water.

Step 3: Heating the Solution

• Transfer the filtered liquid solution into a heat-resistant container.
• Gradually heat the solution to facilitate the neutralization process.
• Monitor the temperature closely to avoid boiling over, aiming for a gentle simmer.

Step 4: Adding the Precipitant

• Once the solution is heated, it’s time to add the precipitant.
• Carefully measure the appropriate amount of precipitant based on the volume of your solution.
• Stir the mixture gently to ensure even distribution of the precipitant.

Step 5: Collecting the Soil

• After the precipitant has reacted, gather the resulting solid material.
• Use a beaker to collect all the settled solids.
• Rinse the collected material with clean water to remove any remaining liquid.

Step 6: Drying the Material

• Spread the wet soil on a clean surface or use a drying tray.
• Allow the soil to air dry completely, or use a low heat source to speed up the drying process.
• Ensure the material is fully dry before proceeding to smelting.

Step 7: Smelting the Gold

• Once the material is dry, prepare for the smelting process.
• Place the dried material in a crucible and apply heat using a furnace or torch.
• Monitor the melting process carefully until you achieve a molten state.

Conclusion

This tutorial covered the essential steps for filtering, washing, neutralizing, and smelting gold from rocks and soil. By following these steps, you can effectively extract gold while minimizing losses. As a next step, consider researching safe practices for handling chemicals and high temperatures during the smelting process to ensure a safe working environment.
