Sand zirconium ore gravity separation process flow

Sand zirconium ore is an important mineral resource widely used in fields such as ceramics, electronics, and aerospace. However, the extraction and processing process of sand zirconium ore is relatively complex, requiring a series of process flows to obtain high-quality sand zirconium ore. This article will introduce the process flow of sand zirconium ore gravity separation to help readers better understand the processing process of sand zirconium ore.

1、 Properties of Sand Zirconium Ore

Zirconite is a sandy mineral containing zirconium, titanium, iron and other elements, and its main components are Zirconium dioxide and silicon dioxide. The color of sand zircon ore appears gray white, yellow, or brown, with a high hardness and a specific gravity between 4.0 and 4.7. The mineral composition of zircon is complex, including zircon, garnet, Apatite, Calcite, Epidote, etc.

2、 The gravity separation process of sand zirconium ore

The processing process of sand zirconium ore mainly includes processes such as crushing, screening, gravity separation, magnetic separation, etc. Among them, the gravity separation process is a key link in the processing of sand zirconium ore. Its main purpose is to separate impurities from sand zirconium ore through physical methods, improve the grade and recovery rate of sand zirconium ore. The following will provide a detailed introduction to the gravity separation process of sand zirconium ore.

1. Rough selection

Rough selection is the first step in the gravity separation process of sand zirconium ore, with the aim of removing large impurities from the sand zirconium ore through vibration screening. In general, the mesh size used for coarse screening is 10-20mm, which results in better screening efficiency. After rough selection, the impurity content in the sand zirconium ore is significantly reduced, and the grade is improved.

2. Successful selection

Intermediate separation is the second step in the sand zirconium ore gravity separation process, with the aim of removing light impurities from the sand zirconium ore through a cyclone or heavy medium separator. In the middle concentration process, zircon ore is suspended in water, and light impurities are separated according to different density differences. In general, the medium used in the selection is water and heavy liquids, such as heavy mineral oil and heavy media.

3. Selection

Selection is the final step in the sand zirconium ore gravity separation process, with the aim of removing fine impurities from the sand zirconium ore through equipment such as vibration tables and inclined plates. During the selection process, the sand zirconium ore is divided into several different particle sizes, and then screened through a vibrating table or inclined plate to obtain high-grade sand zirconium ore. During the selection process, attention needs to be paid to controlling the water flow rate and vibration frequency to ensure the grade and recovery rate of the sand zirconium ore.

3、 Optimization of the gravity separation process for sand zirconium ore

Although the sand zirconium ore gravity separation process is relatively mature, there are still some problems, such as low recovery rate and high energy consumption. In order to solve these problems, it is necessary to optimize the gravity separation process of sand zirconium ore. Below will introduce some common optimization methods.

1. Adopting new gravity separation equipment

The new type of gravity separation equipment has the characteristics of compact structure, low energy consumption, and good sorting effect, which can effectively improve the grade and recovery rate of sand zirconium ore. At present, the commonly used new types of gravity separation equipment include spiral sorting machines, centrifugal sorting machines, airflow sorting machines, etc.

2. Optimize sorting process parameters

The separation process parameters of have an important impact on the grade and recovery rate of sand zirconium ore. By optimizing the sorting process parameters, such as water flow rate, vibration frequency, medium density, etc., the grade and recovery rate of sand zirconium ore can be improved.

3. Adopting advanced automation control system

The use of advanced automation control systems can achieve real-time monitoring and control of the sand zirconium ore gravity separation process, thereby ensuring the grade and recovery rate of sand zirconium ore. The automation control system can monitor the operating status of sorting equipment and adjust it based on real-time data, thereby improving the grade and recovery rate of sand zirconium ore.

4、 Summary

The gravity separation process of sand zirconium ore is a key link in the processing of sand zirconium ore. Its purpose is to separate impurities from sand zirconium ore through physical methods, improve the grade and recovery rate of sand zirconium ore. This article introduces the gravity separation process and optimization methods of sand zirconium ore, hoping to help readers better understand the processing process of sand zirconium ore.
