Gravity beneficiation test of tungsten tailings

Tungsten tailings are an important metal ore with characteristics such as high density, high melting point, and high hardness, which are widely used in industrial production. However, there are a series of problems in the mining and beneficiation process of tungsten tailings, such as low ore grade and fine ore particles, which bring great difficulty to the beneficiation work of tungsten tailings. To address these issues, we conducted gravity beneficiation experiments on tungsten tailings.

1、 Test purpose

The purpose of this experiment is to explore the feasibility of gravity beneficiation of tungsten tailings and optimize the beneficiation process, improve the beneficiation efficiency and grade of tungsten tailings, and provide technical support for actual production.

II. Experimental Principles

gravity beneficiation is a beneficiation method that utilizes the different stress conditions of minerals in the gravity field to separate minerals of different densities. In gravity beneficiation of tungsten tailings, the effect of gravity field is utilized to separate the ore according to density, achieving the goal of improving ore grade and beneficiation efficiency.

3、 Test steps

1. Preparation of ore samples

Firstly, we need to prepare samples of tungsten tailings by mixing the ore in a certain proportion, crushing and screening to obtain ore samples with a particle size of 0.5-1mm.

2. Gravity beneficiation test

Place the prepared ore sample into a gravity concentrator for testing. In the experiment, we used different gravity field intensities and water flow velocities to separate the ore. Based on the separation effect, we continuously adjust the experimental parameters and optimize the beneficiation process.

3. Analysis of test results

After the experiment is completed, we analyze the experimental results. By conducting chemical analysis and physical property testing on the separated ore, data such as ore grade and beneficiation efficiency are obtained. Based on the data analysis results, we have optimized and improved the beneficiation process.

IV. Test Results

After multiple experiments and data analysis, we have determined a relatively optimized gravity beneficiation process for tungsten tailings. Under this process, the grade of tungsten tailings has been significantly improved, and the beneficiation efficiency has also been greatly improved. This process has the advantages of simple operation and low cost, and is suitable for practical production.

5、 Conclusion

The results of the gravity beneficiation test of tungsten tailings at indicate that gravity beneficiation is an effective beneficiation method that can improve the grade and beneficiation efficiency of tungsten tailings. In actual production, tungsten tailings gravity beneficiation process can be used to improve the comprehensive utilization efficiency of tungsten tailings.
