Zircon is a common mineral with high hardness, density, and melting point, making it an important industrial raw material. The beneficiation technology of zircon mainly relies on physical methods for separation, including gravity separation, magnetic separation, and electrical separation. This article will introduce the operating steps and precautions of zircon beneficiation experiments, helping readers better understand the beneficiation technology of zircon.
1、 Preparation before testing
1. Sample preparation: After processing zircon ore through processes such as coarse crushing, fine crushing, and screening, prepare a sample that meets the test requirements.
2. Test equipment: The test equipment includes gravity separators, magnetic separators, electric separators, etc., and suitable equipment needs to be selected according to the test requirements.
3. Test conditions: The test conditions include water volume, sorting speed, sorting time, etc., which need to be adjusted according to the test requirements.
II. Re-selection test
Gravity separation is the first step in zircon beneficiation, which can remove impurities from the ore and improve the grade of zircon. The operating steps for the reselection test are as follows:
1. Place the prepared zircon sample into the gravity separator, add an appropriate amount of water, and turn on the gravity separator.
2. Adjust the sorting speed and sorting time of the gravity separator according to the experimental requirements.
3. After the gravity separation is completed, the gravity concentrate and tailings are taken out for laboratory analysis, and the grade and recovery rate of zircon are calculated.
3、 Magnetic separation test
Magnetic separation is the second step in zircon beneficiation, which can remove magnetic minerals from the ore and improve the grade of zircon. The operating steps of the magnetic separation test are as follows:
1. Place the gravity concentrate into the magnetic separator, add an appropriate amount of water, and turn on the magnetic separator.
2. Adjust the magnetic field strength and sorting speed of the magnetic separator according to the test requirements.
After the magnetic separation is completed, the magnetic separation concentrate and tailings are taken out for laboratory analysis, and the grade and recovery rate of zircon are calculated.
4、 Electrical selection test
Electric separation is the third step in zircon beneficiation, which can remove conductive minerals from the ore and improve the grade of zircon. The operating steps of the electrical selection test are as follows:
1. Place the magnetic separation concentrate into the electric separator, add an appropriate amount of water, and turn on the electric separator.
2. Adjust the electric field strength and sorting speed of the electric separator according to the test requirements.
After the electric separation is completed, the concentrate and tailings of the electric separation are taken out for laboratory analysis, and the grade and recovery rate of zircon are calculated.
5、 Precautions
During the testing process, it is necessary to strictly control the test conditions to ensure the reliability and accuracy of the test.
2. During the testing process, it is necessary to pay attention to safety and avoid accidents.
3. After the test, it is necessary to clean and maintain the testing equipment to ensure its normal operation.
This article introduces the operating steps and precautions of zircon beneficiation experiments, hoping to be helpful to readers. The beneficiation technology of zircon is a complex process that needs to be adjusted and optimized according to the actual situation in order to achieve better results.
