Mineral processing methods for sand zirconium ore

Zirconium ore is an important mineral resource mainly used for manufacturing ceramics, glass, electronic products, etc. The content of sand zirconium ore is low, so the beneficiation process is crucial. This article will introduce several common beneficiation methods for sand zirconium ore.

1、 Heavy medium beneficiation method

The heavy medium beneficiation method is a commonly used beneficiation method, suitable for the larger particle size of sand zirconium ore. This method uses density difference of the heavy medium to separate zircon from impurities. The specific operation steps are as follows:

1. Crush the sand zirconium ore to a certain particle size, usually 0.5-5 millimeters.

2. Mix the crushed sand zirconium ore with a heavy medium, usually with a density of 2.5-3.5g/cm ³。

3. Place the mixture into a heavy medium separator for sorting. During sorting, the heavy medium will sink to the bottom, while the sand zirconium ore will float on top.

4. Clean and dry the sorted sand zirconium ore to obtain a concentrate.

2、 Electroselection method

Electric separation method is a method of separating minerals using electric field force, suitable for the small particle size of sand zirconium ore. This method is easy to operate and has good separation effect. The specific operation steps are as follows:

1. Crush the sand zirconium ore to a certain particle size, usually ranging from 0.1 to 0.5 millimeters.

2. Put the crushed sand zirconium ore into the electric separator, usually using a high-voltage DC power supply.

3. Under the action of an electric field, sand zirconium ore and impurities are separated, sand zirconium ore is collected on the anode, and impurities are collected on the cathode.

4. Clean and dry the sand zirconium ore collected on the anode to obtain the concentrate.

3、 Flotation method

Flotation method is a method of separating minerals by utilizing differences in physical and chemical properties, suitable for small particle sizes of sand zirconium ore. This method is easy to operate and has good separation effect. The specific operation steps are as follows:

1. Crush the sand zirconium ore to a certain particle size, usually ranging from 0.1 to 0.5 millimeters.

2. Mix the crushed sand zirconium ore with reagents, usually oxidants, sulfides, etc.

3. Place the mixture into a flotation machine for flotation, where the zirconium ore will float on top and impurities will settle to the bottom.

4. Clean and dry the flotation sand zirconium ore to obtain a concentrate.

The above three methods are commonly used for beneficiation of sand zirconium ore. Different methods are suitable for different particle sizes of sand zirconium ore. Choosing the appropriate method can improve beneficiation efficiency and reduce costs.
