Zirconium sand selection test

The zirconium sand selection test is a commonly used method for separating and purifying zirconium sand. Zirconium sand is an important mineral resource widely used in fields such as aerospace, nuclear industry, and chemical industry. The zirconium sand selection test can improve the purity and quality of zirconium sand, thereby enhancing its application value. This article will introduce the operating steps and precautions for selecting zirconium sand test.

1、 Experimental principle

The zirconium sand selection test is a method of separating zirconium sand minerals from impurities through gravity separation, magnetic separation, and flotation, in order to improve the purity and quality of zirconium sand. Among them, gravity separation is the most commonly used method, which uses the density difference of minerals for separation. Magnetic separation utilizes the magnetic differences of minerals for sorting, while flotation utilizes the buoyancy differences of minerals for sorting.

2、 Test steps

1. Sample preparation

Grind the ore sample containing zirconium sand into fine powder and obtain a sample with a particle size of 0.074mm through screening. Place the sample in a dryer and dry it at 100 ℃ for 2 hours to completely dry.

2. Gravity sorting

Put the dried sample into the gravity separator and adjust the swing angle and amplitude of the machine to produce appropriate vibration. By gravity separation, minerals containing zirconium sand are separated from impurities. After sorting, place the sorted zirconium sand sample in an oven and dry it for 2 hours at 100 ℃.

3. Magnetic separation

Put the dried zircon sand sample into the magnetic separator, adjust the magnetic field intensity and magnetic induction Linear density of the machine to generate an appropriate magnetic field. By magnetic separation, impurities such as iron containing minerals are separated from zirconium sand. After sorting, place the sorted zirconium sand sample in an oven and dry it for 2 hours at 100 ℃.

4. Flotation

Put the dried zirconium sand sample into the flotation machine, adjust the bubble size and gas flow of the machine to generate appropriate bubbles. By flotation, impurities such as siliceous minerals are separated from zirconium sand. After sorting, place the sorted zirconium sand sample in an oven and dry it for 2 hours at 100 ℃.

5. Detection and analysis

Send the sorted zirconium sand sample to the laboratory for testing and analysis to determine whether its purity and quality meet the requirements.

3、 Precautions

During the sample preparation process, attention should be paid to avoiding moisture and contamination of the sample.

During the processes of gravity separation, magnetic separation, and flotation, attention should be paid to adjusting the machine parameters to produce appropriate separation effects.

3. The sorted zirconium sand samples should be dried to avoid affecting the detection and analysis results.

During testing and analysis, it is important to choose appropriate testing methods and equipment to ensure accurate and reliable testing results.

4、 Conclusion

The zirconium sand selection test is a commonly used method for separating and purifying zirconium sand. By using methods such as gravity separation, magnetic separation, and flotation, minerals containing zirconium sand can be separated from impurities, achieving the goal of improving the purity and quality of zirconium sand. During the experiment, attention should be paid to sample preparation, adjusting machine parameters, drying samples, and testing and analysis to ensure accurate and reliable test results.
