Gravity separation method for titanium iron sand ore

Gravity separation method for titanium iron sand ore

Titanium iron ore is a common mineral resource widely used in fields such as metallurgy, chemical industry, aerospace, etc. However, during the mining and extraction process of titanium iron ore, a large amount of waste and pollutants are often generated, which seriously affect the environment. Therefore, finding an efficient and environmentally friendly gravity separation method for titanium iron ore has become one of the current research hotspots.

1、 Characteristics of titanium iron ore

Ferrotitanium placer is a kind of titanium bearing iron mineral, whose main components are titanium dioxide and iron oxide. Its physical properties are closely related to magnetism, generally in the form of black or brown powder, with a certain degree of magnetism. Titanium iron sand ore has a high hardness and density, with a common grade of 30% to 50%. However, there are also high-grade titanium iron sand ore.

2、 Gravity separation method for titanium iron sand ore

1. Magnetic separation method

Magnetic separation method is a commonly used gravity separation method for titanium iron ore, which utilizes the different behaviors of minerals with different magnetic properties under the action of a magnetic field to separate and extract minerals. Magnetic separation methods are usually divided into two types: dry magnetic separation and wet magnetic separation.

dry magnetic separation is the separation of titanium iron ore powder in a magnetic field. Its advantages are simple equipment and easy operation, but the effect is not good for low grade titanium iron ore.

Wet magnetic separation is the separation of titanium iron ore slurry in a magnetic field. Its advantage is that it is suitable for low-grade titanium iron ore, but the equipment is complex and the operation is difficult.

2. Heavy medium selection method

The heavy medium separation method is a gravity separation method of ferrotitanium ore based on density difference. Its principle is to mix ferrotitanium ore slurry with heavy medium, so that minerals with density greater than heavy medium sink and minerals with density less than heavy medium float, thus realizing the separation and extraction of minerals.

The heavy medium separation method is suitable for low grade titanium iron ore, with simple operation and high efficiency. However, it requires high equipment requirements, and the recovery and treatment of heavy medium is also a challenge.

3. Flotation method

Flotation method is a common mineral separation method, which utilizes the affinity difference between minerals and flotation agents to separate minerals. Titanium iron ore can be separated from other minerals under the action of flotation agents.

The flotation method is suitable for high-grade titanium iron ore, but it has high requirements for the selection and use of flotation agents and has a significant impact on the environment.

3、 Summary

The selection of gravity separation methods for titanium iron ore requires comprehensive consideration based on the characteristics and grade of titanium iron ore. The magnetic separation method, heavy medium separation method, and flotation method all have their advantages and disadvantages, and they need to be selected according to the actual situation. At the same time, in order to reduce the environmental impact during the mining and extraction process of titanium iron ore, it is necessary to strengthen the treatment and recycling of waste, and promote environmentally friendly titanium iron ore gravity separation methods.
