Seashore placer gold re selection test

In recent years, with the development of the economy and the improvement of people's living standards, the demand for gold has been increasing. And coastal placer gold is a common gold ore, and its mining and beneficiation technology has always been a research focus in the mining industry. This article will introduce the operational steps and results of the seaside placer gold gravity separation experiment, in order to provide reference for mining workers.

1、 Experimental principle

The main minerals of coastal placer gold are gold ore, Magnetite, Hematite, Chalcocite, etc. Due to the small particle size of placer gold, it is often mixed with minerals and difficult to separate. Therefore, it is necessary to achieve the separation and extraction of placer gold through re selection technology.

Re-selection is the use of different specific gravity of minerals in water to achieve mineral separation through different flow rates and directions. During the re selection process, it is necessary to achieve the best separation effect by adjusting parameters such as water flow velocity, slope, and water volume.

2、 Test steps

1. Sample collection

Firstly, a certain amount of coastal placer gold samples need to be collected and sent to the laboratory for analysis and testing. The collection of samples should follow scientific methods and norms to ensure the accuracy and reliability of test results.

2. Sand gold rough selection

Roughly select the collected samples and separate the sand gold particles and minerals. Rough selection can use methods such as gravity beneficiation and washing to separate placer gold particles from minerals.

3. Sand gold re selection

After rough selection, the placer gold sample is re selected to achieve the separation of placer gold and minerals through different water flow velocities and directions. During the re selection process, it is necessary to continuously adjust parameters to achieve the best separation effect.

4. Selection of Sand Gold

Select the re selected sand gold samples and further purify the sand gold particles. Selection can use methods such as flotation and gravity beneficiation to separate placer gold particles from impurities.

5. Finished sand gold products

After selection of sand gold, the obtained sand gold products can be directly used for gold extraction or sales. The quality and purity of finished sand gold products have a significant impact on the subsequent process flow and product quality.

III. Test Results

We obtained the following results through the seaside sand gold re selection experiment:

1. The use of gravity separation technology can effectively separate placer gold and minerals, improving the recovery rate and quality of placer gold.

During the re selection process, parameters such as water flow velocity, slope, and water volume have an important impact on the separation effect and need to be continuously adjusted and optimized.

3. Selection of placer gold can further improve the purity and quality of placer gold, providing guarantee for subsequent process flow and product quality.

4、 Conclusion

The seaside placer gold gravity separation test is a common beneficiation technique that can effectively separate placer gold and minerals, improve the recovery rate and quality of placer gold. During the experiment, attention needs to be paid to adjusting and optimizing parameters to achieve the best separation effect. After the selection of placer gold, the obtained placer gold products can be directly used for gold extraction or sales, providing important reference and guidance for mining workers.
