Zircon re selection test

Zircon re selection test is a common metal separation technique that can be used to purify metals such as zirconium and hafnium. In this article, we will introduce the operating steps and principles of zircon re selection test.

Principle of Zircon Re-selection Test

The zircon gravity separation experiment utilizes the differences in physical and chemical properties between zircon minerals and hafnium minerals, and through repeated sorting and separation, ultimately obtaining high-purity products of zirconium and hafnium.

2、 Operating Steps for Zircon Re-selection Test

1. Sample preparation

Firstly, samples containing zircon and hafnium minerals need to be prepared. Grind the sample into powder and screen out the required particle size range.

2. Mineral separation

Add the sample to the flotation cell and add an appropriate amount of reagents such as oxidants, defoamers, etc. for flotation. After multiple floatations and separations, separation products of zircon minerals and hafnium minerals can be obtained.

3. Reselection

Add the separated products of zircon and hafnium minerals to the gravity separation tank, and add an appropriate amount of reagents such as hydrofluoric acid, sulfuric acid, etc. for gravity separation. After multiple re selections and separations, purer products of zirconium and hafnium can be obtained.

4. Selection

Select the re selected products to remove impurities and impure substances. Finally, high-purity zirconium and hafnium products are obtained.

3、 Conclusion

Zircon re selection test is a common metal separation technique that can be used to purify metals such as zirconium and hafnium. Through repeated selection and separation, high-purity products of zirconium and hafnium were ultimately obtained. In practical applications, it is necessary to select appropriate reagents and operating conditions based on specific circumstances to improve separation efficiency and purity.

In summary, zircon gravity separation test is a very important metal separation technology with broad application prospects. I hope this article is helpful to readers.
