Gravity Separation Process Flow of Binhai Zirconium Sand Mine

Binhai zirconium sand ore is an important metal mineral resource widely used in fields such as aerospace, chemical industry, electronics, medicine, etc. However, due to the complex structure and high impurities of zirconium sand ore, it is necessary to undergo a gravity separation process to improve the grade and purity of zirconium sand. This article will introduce the gravity separation process of coastal zirconium sand ore, helping readers better understand the purification process of zirconium sand ore.

1. Preliminary preparation

Before carrying out the gravity separation process of the coastal zirconium sand ore, certain preliminary preparations need to be carried out. Firstly, it is necessary to analyze and test the ore to determine its chemical composition and physical properties. Secondly, it is necessary to perform pre-treatment work such as crushing and screening on the ore in order to facilitate subsequent beneficiation operations.

2、 Re-selection process flow

The gravity separation process of Binhai Zirconium Sand Mine mainly includes grinding, rough selection, intermediate selection, selection, and tailings treatment. The following will provide a detailed introduction to each link.

1. Grinding

Grinding is the first step of the zirconium sand ore gravity separation process, which aims to break the ore into particles of a certain size for subsequent beneficiation operations. There are generally two types of grinding methods: dry grinding and wet grinding. In dry grinding, the ore is crushed and screened through a vibrating screen to obtain particles of a certain size; In wet grinding, the ore is crushed, mixed with a certain amount of water, and then ground through a ball mill to obtain particles of a certain size.

2. Rough selection

Rough separation is the second step of the zirconium sand ore gravity separation process, which aims to separate impurities from low-grade zirconium sand in the ore. The methods of rough selection generally include heavy medium selection, flotation, and magnetic separation. In the heavy medium selection, the ores are separated by the heavy medium with different density to obtain a certain grade of zirconium sand; In flotation, the ore separates zirconium sand and impurities through the action of bubbles to obtain a certain grade of zirconium sand; In magnetic separation, the ore separates magnetic impurities through magnetic differences to obtain a certain grade of zirconium sand.

3. Successful selection

The intermediate selection is the third step of the zirconium sand gravity separation process, with the aim of further improving the grade and purity of zirconium sand. The selection methods generally include heavy medium selection, flotation, and magnetic separation. In heavy medium selection, ores are separated by heavy medium with different density to obtain higher grade zirconium sand; In flotation, the ore separates higher-grade zirconium sand from impurities through the action of bubbles, resulting in higher-grade zirconium sand; In magnetic separation, the ore separates higher-grade zirconium sand through magnetic differences to obtain higher-grade zirconium sand.

4. Selection

selection is the fourth step of the zirconium sand gravity separation process, with the aim of further improving the grade and purity of zirconium sand. The selection methods generally include heavy medium selection, flotation, and magnetic separation. In heavy medium selection, ores are separated by heavy medium with different density to obtain higher grade zirconium sand; In flotation, the ore separates higher-grade zirconium sand from impurities through the action of bubbles, resulting in higher-grade zirconium sand; In magnetic separation, the ore separates higher-grade zirconium sand through magnetic differences to obtain higher-grade zirconium sand.

5. Tailings treatment

Tailings treatment is the final step of the zirconium sand ore gravity separation process, with the aim of treating the waste generated during the beneficiation process to reduce environmental pollution. The methods of tailings treatment generally include flotation, heavy medium separation, and magnetic separation. In flotation, tailings separate useful minerals and impurities through the action of bubbles to obtain a certain grade of tailings; In heavy medium selection, tailings are separated by heavy medium with different density to obtain tailings of certain grade; In magnetic separation, tailings separate magnetic impurities through magnetic differences to obtain a certain grade of tailings.

3、 Summary

Through the above introduction, we can learn about the gravity separation process of Binhai Zirconium Sand Mine. In actual production, it is necessary to select appropriate beneficiation processes based on specific ore properties and production requirements to improve the grade and purity of zirconium sand. At the same time, when conducting mineral processing operations, it is necessary to pay attention to environmental issues, strengthen tailings treatment work, and reduce environmental pollution.
