Zirconium pre selection and enrichment process flow

Zirconium pre selection and enrichment process flow

Zirconium is an important metal element widely used in various fields, such as aerospace, nuclear industry, chemical industry, etc. The extraction and enrichment process of zirconium is one of the important links in the zirconium industry. This article will introduce a zirconium pre selection and enrichment process to help readers better understand the extraction and enrichment process of zirconium.

1、 Overview of Zirconium Preconcentration and Enrichment Process Flow

The zirconium pre selection and enrichment process refers to the process of pre selecting minerals rich in zirconium from zirconium ore and conducting enrichment treatment to obtain high-purity zirconium products. This process mainly includes steps such as ore beneficiation, grinding, flotation, acid leaching, and solution treatment.

2、 Operation steps of zirconium pre selection and enrichment process flow

1. Ore beneficiation

Ore beneficiation refers to the preliminary physical separation of collected zirconium ore to remove impurities and secondary minerals. Common methods include re selection, magnetic separation, manual selection, etc. The ore obtained after beneficiation has a high zirconium content, laying the foundation for subsequent enrichment treatment.

2. Grinding

grinding refers to the fine grinding of the ore after beneficiation to increase the surface area of the ore and facilitate subsequent flotation and acid leaching. Commonly used grinding equipment includes ball mills, mineral mills, etc.

3. Flotation

Flotation refers to the separation of zirconium containing minerals from other minerals by utilizing the differences in physical and chemical properties of mineral surfaces. Common flotation agents include hexadecyl Trimethylamine, hexadecyl trimethyl Ammonium bromide, etc. The zirconium concentrate obtained after flotation has a high zirconium content and can be subjected to subsequent acid leaching and solution treatment.

4. Acid leaching

Acid leaching refers to the dissolution of zirconium minerals from zirconium concentrate using an acidic solution to obtain a solution containing zirconium. Commonly used acid leaching agents include sulfuric acid, hydrofluoric acid, etc. The solution obtained after acid leaching has a high zirconium content and can be subjected to subsequent solution treatment.

5. Solution treatment

Solution treatment refers to the refining and enrichment of zirconium containing solutions to obtain high-purity zirconium products. Common solution treatment methods include solvent extraction, ion exchange, membrane separation, etc. After solution treatment, the purity of the obtained zirconium product can reach over 99.95%.

III. Summary

The zirconium pre selection and enrichment process is one of the indispensable links in the zirconium industry. This process involves steps such as ore beneficiation, grinding, flotation, acid leaching, and solution treatment to extract zirconium minerals from zirconium ore and obtain high-purity zirconium products. In actual production, appropriate process flow and equipment should be selected based on the different characteristics and process requirements of the ore to improve process efficiency and product quality.
