Gravity beneficiation test of tungsten sand

Tungsten sand is an important non-metallic mineral resource with high tungsten content and wide applications. However, due to the uneven distribution of tungsten sand in nature, its mineral processing is difficult. In order to improve the beneficiation efficiency of tungsten sand, the use of gravity beneficiation technology is an effective method. This article will introduce the operational steps and experimental results of tungsten sand gravity beneficiation experiment.

1、 Test materials and equipment

1. Test materials: tungsten sand sample, water, reagent.

2. Test equipment: gravity beneficiation equipment, laboratory flotation machine, laboratory magnetic separator, laboratory vibrating screen, etc.

II. Test Steps

1. Preparation of tungsten sand sample: Crush and grind the tungsten sand sample to obtain a sample with a particle size of 0.074mm.

2. Gravity beneficiation test: After mixing tungsten sand samples with water, beneficiation is carried out using gravity beneficiation equipment. During the test, the tungsten sand can be sorted according to the density difference of tungsten sand, so as to obtain the mineral processing products with high tungsten content.

3. Flotation test: Conduct flotation tests on the products obtained from gravity beneficiation. During the experimental process, tungsten sand can be separated from other minerals by controlling parameters such as reagent dosage and gas flow rate, thereby obtaining mineral processing products with higher tungsten content.

4. Magnetic separation test: Conduct magnetic separation tests on the products obtained from flotation. During the test, the tungsten sand can be separated from other minerals by controlling the magnetic field strength, Magnetic flux density and other parameters, so that the mineral processing products with higher tungsten content can be obtained.

5. Screening test: Conduct screening tests on the products obtained from magnetic separation. During the experimental process, the size of the sieve can be controlled to separate tungsten sand from other minerals, thereby obtaining beneficiation products with higher tungsten content.

III. Test Results

After gravity beneficiation, flotation, magnetic separation, and screening tests, the tungsten sand beneficiation product obtained has a high tungsten content and achieved the expected effect. Meanwhile, by adjusting the parameters during the experimental process, the beneficiation efficiency of tungsten sand can be further improved.

4、 Conclusion

The gravity beneficiation test of tungsten sand is an effective beneficiation method. By adjusting the parameters during the experimental process, the beneficiation efficiency of tungsten sand can be further improved. In actual production, suitable beneficiation processes can be selected based on the characteristics and beneficiation requirements of tungsten sand, thereby improving the yield and quality of tungsten sand.
