Beneficiation test of tungsten tin ore

Tungsten tin ore is an important rare metal ore with extensive application value. Due to its low content, mineral processing is needed to improve its grade to meet industrial production needs. This article will introduce the steps and methods of tungsten tin ore beneficiation experiments to help readers understand the process.

1. Test Purpose

The purpose of this experiment is to improve the grade of tungsten tin ore, reduce impurity content, and meet the requirements of industrial production through mineral processing. At the same time, various indicators in the beneficiation process are tested and analyzed to provide reference for industrial production.

2、 Test equipment

1. Tungsten tin ore beneficiation equipment: including jaw crushers, ball mills, flotation machines, dry separators, etc.

2. Laboratory equipment: including electronic balance, microscope, fluorescence spectrometer, Diffractometer, etc.

3、 Test steps

1. Preparation of ore samples: Crush and grind tungsten tin ore samples to prepare ore samples that meet the test requirements.

2. Chemical analysis of ore samples: Conduct chemical analysis of ore samples to determine their composition and content.

3. Flotation test: Place the prepared ore sample into a flotation machine for flotation testing. During this process, by controlling the type and dosage of reagents, adjusting the concentration of reagents and bubble size, tungsten tin ore and impurity minerals are separated.

4. Dry separation test: Conduct a dry separation test on the tungsten tin ore after flotation. By controlling the amplitude and frequency, tungsten tin ore and impurity minerals are separated.

5. Ore grade testing: Conduct grade testing on the tungsten tin ore after beneficiation to determine its grade and impurity content.

4、 Analysis of test results

Through experiments, we obtained the following results:

The chemical composition of the tungsten tin ore sample: tungsten content is 0.15%, tin content is 0.08%, and other impurities content is relatively low.

2. Flotation test results: under the condition that the reagent types are Sodium acetate, sodium hydroxide and Xanthan gum, the separation effect of tungsten tin ore and impurity minerals is good.

3. Dry separation test results: At an amplitude of 10mm and a frequency of 25Hz, the separation effect of tungsten tin ore and impurity minerals is good.

4. Test results of tungsten tin ore grade: The grade of tungsten tin ore is 0.25%, with low impurity content.

5、 Conclusion

Through this tungsten tin ore beneficiation experiment, we have successfully improved the grade of tungsten tin ore, reduced impurity content, and made it meet the requirements of industrial production. At the same time, we have also obtained test results and analysis of various indicators, providing reference for industrial production.
