Gravity beneficiation process flow of titanium iron tailings

Titanium iron tailings are a common mineral resource, mainly composed of titanium dioxide and iron, and contain a certain amount of other metal elements. Due to its complex composition, gravity beneficiation process is generally used for extraction. This article will introduce the gravity beneficiation process and operating steps of titanium iron tailings.

I. Gravity beneficiation process flow of titanium iron tailings

1. Grinding: grind the titanium iron tailing to make its Granularity meet the requirements.

2. Gravity concentration: gravity concentration treatment is carried out on the titanium iron tailings after grinding, and minerals with different densities are separated by gravity Separation principle. Generally, spiral or centrifugal sorting machines are used for re selection.

3. Magnetic separation: The titanium iron tailings after re separation are subjected to magnetic separation treatment, and magnetic differences are used to separate iron minerals from titanium minerals. Generally, wet magnetic separators are used for magnetic separation.

4. Flotation: The magnetically separated titanium iron tailings are subjected to flotation treatment, and different minerals are separated using differences in physical and chemical properties. Generally, air flotation machines are used for flotation.

5. Cleaning: the flotation ilmenite tailings are cleaned to remove impurities and obtain Ilmenite with high purity.

2、 Operating Steps

1. Grinding: put ferrotitanium tailing into the grinder for grinding treatment, and the grinding time is determined according to the hardness and Granularity of raw materials.

2. Gravity separation: Place the ground titanium iron tailings into a spiral or centrifugal separator for gravity separation treatment. Adjust the speed and tilt angle of the sorting machine according to different mineral densities and particle sizes, so that it can separate minerals with different densities.

3. Magnetic separation: Place the re selected titanium iron tailings into a wet magnetic separator for magnetic separation treatment. Adjust the magnetic field strength and pole position of the magnetic separator based on the magnetic differences of different minerals, so that it can separate iron and titanium minerals.

4. Flotation: Place the magnetically separated titanium iron tailings into an air flotation separator for flotation treatment. Adjust the bubble size and quantity of the flotation machine based on the differences in physical and chemical properties of different minerals, so that it can separate different minerals.

5. Selection: Place the flotation titanium iron tailings into the selection machine for selection treatment. According to the difference of physical and chemical properties of different impurities, adjust the water flow rate and impurity removal device of the concentrator to remove impurities and obtain Ilmenite with high purity.

III. Summary

The gravity beneficiation process of titanium iron tailings includes five steps: grinding, gravity separation, magnetic separation, flotation, and selection. Each step needs to be adjusted and optimized according to the properties and requirements of the raw materials. During the operation process, it is necessary to pay attention to safety and environmental protection to avoid pollution to the environment.
