Gravity beneficiation test of titanium ore

Titanium ore is an important metallic mineral resource widely used in aviation, aerospace, military, chemical, electronics and other fields. In order to improve the grade and recovery rate of titanium ore, gravity beneficiation technology has become an important beneficiation method. This article will introduce the operational steps and experimental results of the titanium ore gravity beneficiation experiment.

1. Test equipment and raw materials

1. Test equipment: gravity concentrator, vibrating screen, magnetic separator, laboratory ball mill, electronic balance, microscope, etc.

2. Test material: Titanium ore, with a grade of TiO2 30.05% and a particle size of 0.074mm.

II. Test Steps

1. Grinding: Grind the titanium ore through a ball mill to a fineness of 0.074mm for subsequent beneficiation experiments.

2. Gravity beneficiation: Place the ground titanium ore into a gravity concentrator for beneficiation experiments. The working principle of a concentrator is to use the differences in specific gravity of different minerals to separate them through water flow. The concentrator is divided into two stages: rough selection and selection. The purpose of rough selection is to separate the ore into heavy and light ores, while the purpose of selection is to separate the titanium ore from the heavy ore. The parameter settings of the concentrator are as follows: feed concentration is 15%, water inflow is 1500L/h, feed particle size is 0.074mm, slope is 5, flushing water pressure is 0.1MPa, titanium ore grade in heavy ore is 37.05%, and recovery rate is 75.06%.

3. Vibration screening: The heavy ore is separated into coarse-grained titanium ore through a vibration screen for subsequent magnetic separation experiments.

4. Magnetic separation: Place the titanium ore separated by the vibrating screen into a magnetic separator for magnetic separation experiments. The working principle of a magnetic separator is to use magnetic materials to adsorb magnetic minerals and separate them from non magnetic minerals. The parameter settings of the magnetic separator are as follows: magnetic field intensity is 0.08T, feed concentration is 15%, water inflow is 1500L/h, feed particle size is 0.074mm, slope is 5, and the grade of titanium ore in heavy ore is 48.15%, with a recovery rate of 85.21%.

5. Analysis of experimental results: Through experiments of gravity and magnetic separation, the grade of titanium ore increased from 30.05% to 48.15%, and the recovery rate increased from 0% to 85.21%. The experimental results indicate that gravity and magnetic separation are effective methods for titanium ore beneficiation, which can improve the grade and recovery rate of titanium ore.

3、 Conclusion

This article introduces the operating steps and experimental results of titanium ore gravity beneficiation experiment. The experimental results show that gravity beneficiation and magnetic beneficiation are effective methods for titanium ore beneficiation, which can improve the grade and recovery rate of titanium ore. In the future, we will further optimize the beneficiation process and improve the comprehensive utilization rate of titanium ore.
