Gravity beneficiation method for beach sand zirconium ore

With the continuous development of technology, the mining and utilization of mineral resources have also been greatly improved. Seashore sand zirconium ore is an important mineral resource, characterized by high zirconium content, good grade, and wide distribution, making it an important industrial raw material. In the mining process of beach sand zirconium ore, gravity beneficiation method is a widely used technology. This article will introduce the operational steps and advantages of the gravity beneficiation method for beach sand zirconium ore.

1、 Characteristics of Seashore Sand Zirconium Mine

Beach sand zircon ore refers to the zircon ore deposited on the beach, mainly composed of zircon and quartz. The main characteristics of the Haibin Sand Zircon Mine are high zircon content, good grade, wide distribution, stable composition, and single mineral composition. Therefore, coastal zirconium ore is an important industrial raw material, widely used in aviation, military, electronics, chemical and other fields.

2、 The principle of gravity beneficiation method

Gravity beneficiation is a kind of separation method that utilizes the difference of gravity and density of minerals. Under the action of gravity field, minerals with different densities will produce different settling velocities, thus achieving mineral sorting. The gravity beneficiation method mainly includes steps such as gravity separation, desliming, intermediate separation, and selection.

III. Operating Steps of Gravity Beneficiation Method for Seashore Sand Zirconium Mine

1. Screening of raw ore

Firstly, it is necessary to screen the raw ore and divide it into different particle sizes. Generally speaking, the smaller the particle size, the smaller the density difference of minerals. Therefore, it is necessary to select appropriate screening particle size according to the actual situation.

2. Reselection

Feed the screened ore into the gravity separator for sorting. In a gravity separator, the ore is subjected to the action of water flow and gravity, and minerals of different densities will have different settling velocities, thus achieving mineral separation. Generally speaking, the beneficiation efficiency of a gravity concentrator is high, which can remove most of the impurities in the ore.

3. Desliming

After re selection, the ore still contains a certain amount of debris, which requires desliming treatment. Desliming methods mainly include Hydrocyclone, spiral separator, etc. During the desilting process, attention should be paid to controlling the water flow and concentration to avoid affecting the ore.

4. Successful selection

After desliming, the content of zircon in the ore is already high, but it still contains a certain amount of impurities. Therefore, the selection process needs to be carried out. The main methods of selection include heavy medium separation, flotation, magnetic separation, etc. Heavy medium separation is a commonly used method that can effectively separate zircon and impurities.

5. Selection

After selection, the content of zircon in the ore is already very high, but there is still a certain amount of impurities. Therefore, selective processing is required. The selected methods mainly include centrifuges, vibrating screens, etc. During the selection process, it is necessary to pay attention to controlling the vibration amplitude and frequency to avoid affecting the ore.

Advantages of Gravity Beneficiation Method

1. High beneficiation efficiency

Gravity beneficiation method can perform multiple beneficiation of ore, thereby improving beneficiation efficiency. In the gravity beneficiation of beach sand zirconium ore, the gravity concentrator has a higher beneficiation efficiency and can remove most of the impurities in the ore.

2. Simple process flow

The process flow of gravity beneficiation method is relatively simple and does not require complex equipment and technology. In the gravity beneficiation of seaside sand zirconium ore, only basic steps such as gravity separation, desliming, intermediate separation, and selection are required.

3. Low cost

The cost of gravity beneficiation method is relatively low and does not require a large amount of energy and manpower input. In the gravity beneficiation of beach sand zirconium ore, only some basic equipment and tools are needed.

5、 Conclusion

The gravity beneficiation method of beach sand zirconium ore is a widely used technology, with its advantages of simple operation steps, high beneficiation efficiency, and low cost, making it one of the main methods for beach sand zirconium ore mining. In practical operation, it is necessary to select appropriate beneficiation methods based on the characteristics and actual situation of the ore, in order to improve beneficiation efficiency and economic benefits.
