Method for gravity separation of titanium iron tailings

Titanium iron tailings are a common ore mineral that has wide applications in metallurgy, chemical industry, and other fields due to its high titanium and iron content. However, there are many impurities in the titanium iron tailings, which require re selection to improve their quality. This article will introduce the method of gravity separation of titanium iron tailings.

1、 Flotation method

Flotation method is a common method for heavy separation of titanium iron tailings, which uses bubbles to combine impurities in titanium iron tailings with bubbles, thereby achieving separation. The specific operation steps are as follows:

1. Grind the titanium iron tailings to a certain fineness, usually below -200 mesh.

2. Add the ground titanium iron tailings to the flotation cell and add an appropriate amount of reagents, such as collectors, foaming agents, etc.

3. Start the flotation equipment to allow bubbles to enter the flotation cell and combine with impurities in the titanium iron tailings.

4. By adjusting parameters such as reagent dosage, bubble size, and stirring speed, the maximum degree of binding between impurities and bubbles is achieved, thus achieving separation.

5. Collect flotation concentrate and tailings for further processing and treatment.

2、 Heavy medium selection method

The heavy medium separation method is a method of separating titanium iron tailings using heavy media. Its principle is to use the difference in specific gravity of heavy media to separate impurities in titanium iron tailings from titanium iron tailings. The specific operation steps are as follows:

1. Grind the titanium iron tailings to a certain fineness, usually below -200 mesh.

2. Add the ground titanium iron tailings to the heavy medium separation equipment, and add an appropriate amount of heavy medium, such as magnetic separation fluid, heavy medium sand, etc.

3. Start the equipment, and separate impurities in ferrotitanium tailings from heavy media by adjusting equipment parameters, such as medium density, flow rate, etc.

4. Collect impurities in the heavy medium and titanium iron tailings in the heavy medium for further processing.

3、 Magnetic separation method

Magnetic separation method is a method of separating titanium iron tailings using magnetic materials. Its principle is to use magnetic materials to adsorb magnetic impurities in titanium iron tailings, thereby achieving separation. The specific operation steps are as follows:

1. Grind the titanium iron tailings to a certain fineness, usually below -200 mesh.

2. Add the ground titanium iron tailings to the magnetic separation equipment and add an appropriate amount of magnetic materials, such as magnetic separators, high gradient magnetic separators, etc.

3. Start the equipment and adjust its parameters, such as magnetic field strength and magnetic material dosage, to enable the magnetic material to adsorb magnetic impurities in titanium iron tailings.

Collect impurities in magnetic materials and titanium iron tailings in magnetic materials for further processing.

In summary, the gravity separation methods for titanium iron tailings mainly include flotation, heavy medium separation, and magnetic separation. Different methods are suitable for different titanium iron tailings, and the specific selection method needs to be adjusted according to the actual situation. By using reasonable re selection methods, the quality of titanium iron tailings can be improved and their application value in metallurgy, chemical industry, and other fields can be enhanced.
