Coarse selection method for coastal zirconium titanium ore

Coastal zircon titanium ore is an important mineral resource, which mainly includes zircon and Ilmenite. Due to its widespread application in aviation, aerospace, military and other fields, the demand for coastal zirconium titanium ore is increasing. Therefore, how to efficiently carry out rough selection of coastal zirconium titanium ore has become an urgent problem that mining enterprises need to solve.

This article will introduce several common rough beneficiation methods for coastal zirconium titanium ore to help mining enterprises improve beneficiation efficiency.

I. Heavy medium beneficiation method

The heavy medium beneficiation method is a common coarse separation method for coastal zirconium titanium ore, which uses media of different densities to separate the ore. Usually, we choose heavy liquid as the medium and place the ore in the heavy liquid, waiting for separation. In heavy liquid, the density is greater than 2.8g/cm ³ The ore will sink into the bottom of the liquid, with a density of less than 2.8g/cm ³ The ore will float on the surface of the liquid. In this way, we can separate zircon from Ilmenite.

The advantage of heavy medium beneficiation method is that it has good separation effect and is not easily affected by the particle size and shape of the ore. Meanwhile, this method is easy to operate and master, and can be applied to different types of ores. However, the heavy medium beneficiation method also has some drawbacks, such as requiring a large amount of medium, resulting in resource waste, and the environmental protection issues in the treatment process also need to be taken seriously.

II. Gravity magnetic separation method

The gravity magnetic separation method is a rough separation method that utilizes the magnetic differences of the ore itself for separation. Under the action of a magnetic field, minerals with different magnetic properties are subjected to different magnetic forces, thereby achieving separation. Usually, we choose strong magnetic substances as the separation medium, such as neodymium iron boron magnets, to separate the ore in a magnetic field.

The advantage of the gravity magnetic separation method is that it has good separation efficiency and is not easily affected by the particle size and shape of the ore. Meanwhile, this method is easy to operate and master, and can be applied to different types of ores. However, the heavy magnetic beneficiation method also has some drawbacks, such as requiring a large amount of magnets, resulting in resource waste, and the environmental protection issues in the treatment process also need to be taken seriously.

3、 Heavy flotation beneficiation method

Gravity flotation is a rough separation method that uses the density difference of ore itself to separate. Under the action of flotation agents, minerals with high density will settle at the bottom of the liquid, while minerals with low density will float on the surface of the liquid. The separation of zircon and Ilmenite can be realized by controlling the type and amount of flotation reagents.

The advantage of heavy flotation beneficiation method is that it has good separation effect and is not easily affected by the particle size and shape of the ore. Meanwhile, this method is easy to operate and master, and can be applied to different types of ores. However, the heavy flotation beneficiation method also has some drawbacks, such as the need for a large amount of flotation reagents, resulting in resource waste, and the environmental protection issues in the treatment process also need to be taken seriously.

In summary, the heavy medium beneficiation method, heavy magnetic beneficiation method, and heavy flotation method are currently common methods for coarse separation of coastal zirconium titanium ores. Each method has its advantages and disadvantages, and it is necessary to select the appropriate method for rough selection based on the actual situation. At the same time, in the process of rough ore selection, it is also necessary to pay attention to environmental issues and minimize waste and pollution.
