Technological process of coastal Tantalite ore dressing

Seaside Tantalite is an important tantalite iron ore, which contains tantalum and iron elements that can be widely used in electronics, metallurgy, chemical industry and other fields. In the process of ore beneficiation, it is necessary to use certain technological processes to improve the grade and recovery rate of the ore. This paper will introduce the beneficiation process of Haibin Tantalite to help readers better understand the processing process of the ore.

1、 Properties of coastal Tantalite

Coastal Tantalite is a kind of black crystal, which usually presents massive, flaky or granular shape. Its main components are Tantalite, iron tantalite, Ilmenite, Columbite, etc. Among them, Tantalite is the mineral with the highest content in coastal Tantalite, and its tantalum content can reach more than 20%.

II. Beneficiation process flow of seaside Tantalite

1. Rough selection

The roughing of coastal Tantalite ore generally adopts gravity concentration method. Firstly, the ore is crushed and then subjected to gravity separation using a gravity separator to remove most impurities such as quartz and feldspar from the ore, resulting in a coarse separation product.

2. Grinding

Grind the rough selected products to a certain particle size. Generally, ball mills are used for grinding, and the product obtained after grinding is called grinding slurry.

3. Flotation

The grinding pulp is flotation treated, and valuable minerals such as Tantalite and iron tantalite are separated from waste rock. During the flotation process, reagents are required, usually including collectors and foaming agents.

4. Cleaning

Clean the flotation products to remove foam and impurities, and obtain dry mineral processing products. During the cleaning process, two methods are required: water washing and mechanical cleaning.

5. Selected

Select the beneficiation products to improve their grade and recovery rate. During the selection process, methods such as gravity separation, magnetic separation, and electrical separation need to be used.

3、 Application of Seaside Tantalite

Tantalum and iron in seaside Tantalite are widely used in electronics, metallurgy, chemical industry and other fields. Among them, tantalum is mainly used for manufacturing capacitors, superconducting materials, alloys, etc., while iron is mainly used for manufacturing steel, alloys, etc.

Summary

The beneficiation process flow of Haibin Tantalite includes such steps as roughing, grinding, flotation, cleaning and concentration. Through the processing of these processes, the grade and recovery rate of the ore can be improved, making it better applied in various fields.
