Method for selecting zirconium ore from sand

Zirconia is an important mineral resource, which is widely used in ceramics, electronics, optics, aerospace, military and other fields. Beneficiation is one of the Committed step of extracting sand zircon. The correct method of selecting sand zircon can improve the grade and recovery of ore, so as to achieve higher economic benefits. This article will introduce several common methods for selecting sand zirconium ore to help readers better understand the beneficiation technology of sand zirconium ore.

1、 Reselection method

The gravity separation method is a commonly used method for selecting zirconium ore, which mainly utilizes the difference in density between zirconium ore and other minerals for separation. The specific operation steps are as follows:

1. After crushing, grinding and other processes, the ore is processed to obtain coarse ore.

2. The coarse ore is separated by a gravity separator, which can choose from flotation machines, centrifuges, spiral separators, etc.

3. The separated sand zirconium ore is further processed through processes such as magnetic separation, electric separation, and gravity separation to improve grade and recovery rate.

The advantage of the gravity separation method is that it has a wide range of applications, can handle various types of sand zirconium ore, and the operation is simple. However, its disadvantage is that there is a lot of waste generated during the beneficiation process, which has a certain impact on the environment.

2、 Fluorination method

Fluorination method is a relatively new method for selecting zirconium ore, which mainly utilizes the differences between zirconium ore and other minerals in the fluorination reaction for separation. The specific operation steps are as follows:

1. After crushing, grinding and other processes, the ore is processed to obtain coarse ore.

2. Mix the coarse ore with a fluorinating agent for fluorination reaction, and the sand zirconium ore will be fluorinated into zirconium fluoride, while other minerals will not undergo fluorination reaction.

3. Hydrolyze and precipitate the fluorinated product to obtain high-purity sand zirconium ore.

The advantage of fluorination method is that it has good beneficiation effect, can obtain high-purity sand zirconium ore, and has less environmental pollution. However, its disadvantage is that the operation is relatively complex, requiring the use of special fluorinating agents and equipment.

3、 Flotation method

Flotation method is a commonly used method for selecting zirconium ore, which mainly utilizes the differences in hydrophilicity and hydrophobicity between zirconium ore and other minerals under the action of flotation agents for separation. The specific operation steps are as follows:

1. After crushing, grinding and other processes, the ore is processed to obtain coarse ore.

2. Mix the coarse ore with the flotation agent to produce bubbles and separate the zirconium ore from other minerals.

3. Further processing such as magnetic separation, electrical separation, and gravity separation will be carried out on the flotation products to improve the grade and recovery rate.

The advantages of the flotation method are good beneficiation efficiency and simple operation, but its disadvantages are the strict selection of flotation agents and the high amount of waste generated during the beneficiation process.

This article introduces several common methods for selecting zirconium ore from sand, each of which has its own advantages and disadvantages. It is necessary to choose the appropriate method based on the specific situation. In the beneficiation process, it is also necessary to pay attention to protecting the environment, reducing the generation of waste residue, improving resource utilization, and achieving sustainable development.
