Technology of selecting beach sand zirconium ore

With the continuous development of technology and the increasing demand for quality of life, the application of zirconium ore is becoming increasingly widespread. The coastal sand zirconium ore is an important source of zirconium ore, and the development of its mining and beneficiation technology is of great significance for the development of the zirconium ore industry. This article will introduce the relevant content of the technology for selecting beach sand zirconium ore.

Characteristics of Seashore Sand Zirconium Mine

Seashore zirconium ore refers to the sand ore containing zirconium minerals distributed in beaches, estuaries, waterways, coasts, and other places. Its main mineral is zircon, and it also contains quartz, titanium ore, Rutile and other impurity minerals. Haibin sand zircon ore is characterized by fine mineral particle size, wide distribution of mineral Granularity, strong mineral adhesion and small difference in mineral density.

2、 Beneficiation methods of beach sand zirconium ore

1. Reselection method

Gravity separation method is a traditional method of mineral processing, suitable for minerals with particle size greater than 0.1mm. This method separates minerals through the action of gravity, usually using a heavy medium concentrator for separation. However, due to the fine particle size of the coastal sand zirconium ore, the beneficiation effect of the gravity separation method is poor.

2. Electric separation method

The electrical separation method is a method of sorting by utilizing differences in mineral conductivity. This method is suitable for minerals with particle size less than 0.1mm. The zircon in the seaside sand zirconium ore has good conductivity, so the electric separation method is an effective method for selecting the seaside sand zirconium ore. The equipment of the electric separation method includes high-voltage electric fields, conveyor belts, collectors, etc.

3. Flotation method

Flotation method is a method of separation that utilizes the difference in affinity between minerals and bubbles. This method is suitable for minerals with particle size less than 0.05mm. The affinity between zircon and bubbles in seaside sand zircon ore is weak, so flotation method is an effective method for selecting seaside sand zircon ore. The equipment of flotation method includes flotation machine, bubble generator, collector, etc.

3、 The beneficiation process of beach sand zirconium ore

The beneficiation process of seaside sand zirconium ore mainly includes steps such as crushing, grinding, grading, flotation, etc. The specific process is as follows:

1. Crushing: Crushing raw ore into appropriate particle size through crushing equipment, usually using equipment such as jaw crushers and cone crushers.

2. Grinding: Grinding the crushed ore to improve the beneficiation effect. Usually, equipment such as ball mills and grinding machines are used.

3. Grading: The finely ground ore is graded to facilitate subsequent beneficiation operations. Usually, equipment such as spiral classifier and hydrocyclone classifier are used.

4. Flotation: Flotation of graded ore to separate useful minerals such as zircon. Usually, flotation machines are used for sorting.

4、 Development Trend of Seashore Sand Zirconium Ore Selection Technology

With the continuous progress of technology and the increasing demands of people for quality of life, the technology of selecting beach sand zirconium ore is also constantly developing. In the future, the development trend of selecting beach sand zirconium ore technology mainly includes the following aspects:

1. Refinement: Further refine the beneficiation process to improve beneficiation efficiency.

2. Automation: Adopting automation equipment to reduce manual operations and improve production efficiency.

3. Greenization: Adopting environmentally friendly equipment to reduce environmental pollution.

4. Integration: Integrate the beneficiation process to improve production efficiency.

5、 Conclusion

The coastal sand zirconium ore is an important source of zirconium ore, and the development of the technology for selecting the coastal sand zirconium ore is of great significance for the development of the zirconium ore industry. The beneficiation methods include gravity separation, electric separation, and flotation, and the beneficiation process includes steps such as crushing, grinding, grading, and flotation. In the future, the development trends of the technology for selecting coastal zirconium ore mainly include refinement, automation, greening, and integration.
