Gravity beneficiation method for zircon sand

Zircon sand is an important mineral resource widely used in fields such as ceramics, glass, electronics, etc. The gravity beneficiation method of zircon sand is a common beneficiation method. This article will introduce the operating steps and precautions of the zircon sand gravity beneficiation method.

1、 Operating steps of gravity beneficiation method for zircon sand

1. Ore crushing: Crush the zircon sand raw ore to achieve a certain particle size requirement. Generally speaking, the particle size requirement for zircon sand raw ore is 0-5mm.

2. Ore screening: Screen the crushed zircon sand raw ore to separate ores of different particle sizes.

3. Gravity separation: The screened zircon sand raw ore is subjected to gravity separation to separate minerals of different densities. Generally speaking, the main minerals in zircon sand are zircon and quartz, and the density of zircon is higher than that of quartz. Therefore, zircon and quartz can be separated by gravity beneficiation.

4. Flotation: Flotation is carried out on the selected zircon sand to remove impurities and non-metallic minerals.

5. Selection: After flotation, the zircon sand is selected to remove iron and titanium minerals to meet the requirements of industrial grade.

2、 Precautions for gravity beneficiation of zircon sand

During the process of ore crushing and screening, attention should be paid to maintaining the integrity of the ore to avoid damage to the minerals in the ore.

2. In the process of gravity separation, it should be adjusted according to the density difference between zircon and quartz to ensure the separation effect.

During the flotation process, attention should be paid to controlling the amount of reagents used and the flotation time to avoid damage to the ore.

During the selection process, attention should be paid to controlling the selection conditions to ensure that the quality of zircon sand meets the requirements of industrial grade.

In summary, the gravity beneficiation method of zircon sand is a common beneficiation method. Through the above operating steps and precautions, zircon and quartz can be effectively separated, meeting the requirements of industrial grade.
