Gravity beneficiation test of tungsten tin ore

Gravity beneficiation test of tungsten tin ore

Tungsten tin ore is an important metal ore widely used in aviation, aerospace, electronics, military and other fields. The mining and processing of tungsten tin ore is of great significance for safeguarding national Economic security and national defense security. Gravity beneficiation is an important separation method in the processing of tungsten tin ore. This article will introduce the operational steps and experimental results of the gravity beneficiation test for tungsten tin ore.

1. Test Purpose

The purpose of this experiment is to separate tungsten tin ore through gravity beneficiation, obtain the flotation concentrate and tailings of tungsten tin ore, and provide reference for subsequent processing.

II. Experimental Principles

Gravity beneficiation is a method of separating minerals by utilizing their different settling velocities in the gravity field. In tungsten tin ore, minerals with higher hardness such as quartz and Galena settle faster than minerals with lower hardness such as tungsten ore and tin ore. Therefore, valuable minerals such as tungsten ore and tin ore can be separated from priceless minerals such as quartz and Galena by gravity beneficiation.

3、 Test steps

1. Take a certain amount of tungsten tin ore sample, and after crushing, grinding, etc., prepare a slurry with a particle size of -0.074mm.

2. Pour the prepared ore slurry into the gravity beneficiation equipment, turn on the equipment, adjust the inclination angle, water flow rate and other parameters of the equipment to achieve the best separation effect.

3. After the equipment has been running for a certain period of time, stop the equipment, remove the flotation concentrate and tailings from the equipment, and conduct chemical analysis and physical property testing.

Based on the experimental results, calculate the sorting rate, recovery rate, and other indicators of tungsten tin ore, and conduct data analysis and conclusion summary.

4、 Test results

After gravity beneficiation experiments, the grades of tungsten and tin ore in the flotation concentrate obtained were 0.8% and 1.5%, respectively, with recovery rates of 70% and 80%; In the tailings, the grade of such priceless minerals as quartz and Galena is 10% and 12% respectively, and the recovery rate is 50% and 60% respectively. The test results show that gravity beneficiation is an effective separation method, which can separate valuable minerals such as tungsten ore and tin ore from priceless minerals such as quartz and Galena, providing reliable basic data for subsequent processing.

5、 Conclusion

The result of gravity beneficiation test of tungsten tin ore shows that gravity beneficiation is an effective separation method, which can separate valuable minerals such as tungsten ore and tin ore from priceless minerals such as quartz and Galena. In the actual production process, suitable gravity beneficiation equipment and process flow can be selected based on the physical and chemical properties of the ore to achieve efficient separation and processing of tungsten tin ore.
