Zirconium sand selection test

The zirconium sand selection test is a common experimental method used to separate zirconium sand and other minerals. This article will introduce the detailed steps and precautions for selecting zirconium sand test.

1、 Experimental Principles

The zirconium sand selection test takes zirconium sand as the target mineral and separates zirconium sand and other minerals through methods such as gravity separation and flotation. Zirconium sand has high specific gravity and good chemical stability, making it widely used in many fields, such as ceramics, electronics, aviation, etc.

2、 Experimental steps

1. Sample preparation

Grind the ore sample to an appropriate particle size, usually below -200 mesh. Then dry the sample for subsequent experimental operations.

2. Reselection

Add the sample to the reselection machine and perform the reselection operation. A gravity separator is a device that uses principles such as gravity and centrifugal force to separate minerals. During the re selection process, zirconium sand will settle to the bottom, while other minerals will float on top.

3. Oxidation roasting

Conduct oxidation roasting treatment on the re selected zirconium sand sample. Oxidative roasting can remove impurities from zirconium sand, resulting in higher purity of zirconium sand. The roasting temperature is generally around 800 ℃ and the time is 2-3 hours.

4. Flotation

Add the roasted zirconium sand sample to the flotation cell for flotation operation. Flotation is a method of separation that utilizes differences in mineral surface properties. During the flotation process, the zirconium sand sample after oxidation roasting is added to the flotation cell, and an appropriate amount of reagent is added. After stirring evenly, the zirconium sand will float on top, while other minerals will settle to the bottom.

5. Washing and drying

Wash and dry the flotation zirconium sand sample. Washing can remove the reagents from the flotation cell, making the zirconium sand more pure. Drying can dry the zirconium sand sample to appropriate moisture for subsequent experimental operations.

3、 Precautions

During the experiment, attention should be paid to safety to avoid accidents.

2. Sample preparation should pay attention to particle size and dryness to ensure the accuracy of experimental results.

3. During operations such as re selection and flotation, attention should be paid to the dosage of reagents and stirring time to ensure experimental results.

4. The oxidation roasting temperature and time should be adjusted according to the actual situation to ensure the roasting effect.

5. After the experiment, the experimental equipment should be cleaned in a timely manner to keep it clean and tidy.

4、 Summary

The zirconium sand selection test is a common experimental method used to separate zirconium sand and other minerals. This article introduces the detailed steps and precautions for selecting zirconium sand test, hoping to be helpful to readers.
