Beneficiation test of zircon ore

Beneficiation test of zircon ore

Zircon ore is an important industrial mineral widely used in ceramics, coatings, electronics, aerospace and other fields. In the mining and utilization process of zircon ore, beneficiation is a very important step. This article will introduce the operating steps and precautions of zircon ore beneficiation experiments, helping readers understand the basic knowledge of zircon ore beneficiation.

1、 Preparation before testing

1. Sample processing

Firstly, it is necessary to process the zircon ore sample for testing. The specific steps of sample processing include sample crushing, screening, washing, and drying. The purpose of sample crushing is to convert large pieces of zircon ore into smaller particles for convenient subsequent processing. The purpose of screening is to separate zircon ores with different particle sizes for different experiments. The purpose of washing is to remove impurities and dust from the surface of the sample to avoid affecting the test results. The purpose of drying is to dry the washed sample for subsequent weighing and mixing.

2. Preparation of testing equipment

The testing equipment includes: beneficiation machine, oscillating screen, centrifuge, drying oven, electronic balance, etc. Before the test, it is necessary to check whether the equipment operates normally, so as not to affect the test results.

II. Test Steps

1. Grinding test

Grinding test is the first step of zircon ore beneficiation test. The purpose of the grinding test is to grind zircon ore into fine powder with a certain particle size for subsequent beneficiation tests. The specific steps of the grinding test include weighing a certain amount of zircon ore sample, adding a certain amount of water and abrasive, and placing it in a grinding machine for grinding. The grinding time is generally 20-30 minutes, and after grinding, screening is required to divide the ground zircon powder into particles of different particle sizes.

2. Flotation test

Flotation test is one of the important steps in zircon ore beneficiation test. The purpose of flotation tests is to separate zircon ore from other impurities in order to improve the grade and recovery rate of zircon ore. The specific steps of the flotation test include placing the ground zircon powder into the flotation machine, adding a certain amount of reagent, mixing, and stirring. The type and dosage of the medication depend on the specific situation. After a certain period of flotation, zircon ore is separated from other impurities, zircon ore floats on the liquid surface to form zircon flotation foam, and impurities sink to the bottom. Then, the flotation foam of zircon ore is collected, dried and weighed, and the grade and recovery of zircon ore are calculated.

3. Magnetic separation test

Magnetic separation test is another important step in zircon ore beneficiation test. The purpose of magnetic separation test is to separate zircon ore from other magnetic impurities, in order to improve the grade and recovery rate of zircon ore. The specific steps of the magnetic separation test include placing the ground zircon powder into a magnetic separator, adding a certain amount of water and magnetic sorting agent, mixing and stirring. The type and dosage of magnetic sorting agents depend on the specific situation. After a certain period of magnetic separation, zircon ore is separated from other magnetic impurities, and zircon ore is adsorbed on the magnetic pole by magnetic sorting agents, while other impurities are excluded. Then, dry and weigh the zircon ore in the magnetic sorting agent, and calculate the grade and recovery rate of the zircon ore.

3、 Test precautions

1. Sample processing should be meticulous

Sample processing is one of the important steps in the beneficiation test of zircon ore, and it should be meticulous and careful. Sample crushing, screening, washing, and drying should be strictly carried out in accordance with the prescribed steps to ensure the purity and particle size of the sample.

2. The testing equipment should operate normally

The testing equipment should be regularly inspected to ensure normal operation. When the equipment malfunctions, it should be repaired or replaced in a timely manner to avoid affecting the test results.

3. Reagents and sorting agents should be used correctly

The types and dosage of reagents and sorting agents should be determined based on specific circumstances, and they should be used according to the specified methods and dosage to avoid affecting the test results.

4. The test results should be accurately calculated

The experimental results should be accurately calculated, including the grade and recovery rate of zircon ore. When calculating, attention should be paid to unit conversion and accuracy control to ensure the accuracy of the results.

4、 Conclusion

The beneficiation test of zircon ore is an important link in the process of zircon ore mining and utilization. Through steps such as grinding, flotation, and magnetic separation, zircon ore can be separated from other impurities, improving the grade and recovery rate of zircon ore. When conducting experiments, attention should be paid to issues such as sample processing, testing equipment, use of reagents and sorting agents to ensure the accuracy of the test results.
