Tungsten tin ore gravity separation test

Tungsten tin ore is an important metal ore widely used in various fields, such as aerospace, electronics, military, and so on. However, there are some difficulties in the mining and processing of tungsten tin ore, one of which is ore gravity separation. To solve this problem, we conducted a tungsten tin ore gravity separation experiment, and the process and results of the experiment will be introduced below.

Background of the experiment

The gravity separation of tungsten tin ore refers to the separation of impurities from the ore through physical or chemical methods, thereby improving the grade and recovery rate of tungsten tin ore. The traditional gravity separation methods mainly include heavy medium separation and flotation, but these methods have some problems, such as low beneficiation efficiency, complex process, and environmental pollution. Therefore, we need to find a more efficient and environmentally friendly reselection method.

Test purpose

The purpose of this experiment is to explore a new method of tungsten tin ore gravity separation, improve beneficiation efficiency and recovery rate, and reduce the impact on the environment.

Test process

1. Preparation of test materials

We selected a type of tungsten tin ore as the experimental material, which mainly consists of tungsten, tin, iron, copper, etc. Firstly, we ground and screened the ore to obtain mineral powder with a particle size of 0.074mm.

2. Test condition settings

We used a new type of gravity separation equipment for the experiment, which combines high intensity magnetic field and airflow separation method, which can effectively separate impurities in the ore. The test conditions are as follows:

Magnetic field strength: 0.8T

Air flow speed: 2m/s

Feed concentration: 20%

3. Test operation steps

(1) Feed the mineral powder into the gravity separation equipment through a vibrating feeder.

(2) Turn on the magnetic field and airflow for sorting.

(3) After the sorting is completed, the sorted ore and impurities will be collected separately.

4. Analysis of test results

After testing, we obtained the following results:

(1) The grade of the ore has been significantly improved, from the original 0.5% to 2.5%.

(2) The recovery rate of ore has also been improved, from the original 50% to 80%.

During the test process, no pollutants were generated and there was no impact on the environment.

conclusion

This experiment has proven the effectiveness of the new gravity separation equipment in tungsten tin ore gravity selection, which can improve beneficiation efficiency and recovery rate, while reducing the impact on the environment. We believe that in further research and development, this device will be widely used.
