Method of Seaside Tantalite Separation

Seaside Tantalite is an important mineral resource. Its main component is tantalite, which contains rich tantalum and iron elements and is an important raw material for manufacturing high-tech products. In the process of developing and utilizing mineral resources, it is very important to choose appropriate beneficiation methods. This paper will introduce some methods of separating seashore Tantalite.

1、 Reselection method

Gravity separation method is a commonly used mineral processing method, which mainly separates ores based on their weight differences. For seaside Tantalite, its main component is tantalite, and the density of tantalite is relatively large, so it can be separated by gravity. The operating steps of the reselection method are as follows:

1. Crush the ore into a certain particle size, usually 0.5-1mm.

2. Place the ore into a gravity separator for sorting, which uses water flow to divide the ore into two parts: heavy and light.

3. Collect the heavy ore and light ore separately. The heavy ore contains more tantalum iron ore, which can be further extracted.

2、 Magnetic separation method

Magnetic separation method is also a commonly used mineral processing method, which mainly separates ores based on their magnetic differences. For seashore Tantalite, its main component is tantalite, and Tantalite has certain magnetism, so it can be separated by magnetic separation. The operating steps of magnetic separation method are as follows:

1. Crush the ore into a certain particle size, usually 0.5-1mm.

2. Place the ore into a magnetic separator for sorting. The working principle of the magnetic separator is to use a magnetic field to divide the ore into two parts: magnetic and non magnetic.

3. Collect magnetic ore and non-magnetic ore separately. Magnetic ore contains more tantalum iron ore, which can be further extracted.

3、 Flotation method

Flotation method is also a commonly used mineral processing method, which mainly separates ores based on their buoyancy differences. For seaside Tantalite, its main component is tantalite, and Tantalite has a certain buoyancy, so it can be separated by flotation. The operation steps of the flotation method are as follows:

1. Crush the ore into a certain particle size, usually 0.5-1mm.

2. Place the ore into a flotation machine for sorting. The working principle of the flotation machine is to use bubbles to divide the ore into two parts: flotation ore and settling ore.

3. Collect flotation ore and settling ore separately. The flotation ore contains more tantalum iron ore, which can be further extracted.

4、 Chloride process process

Chloride process process is a relatively complex mineral processing method, which is mainly separated by the chemical properties of ores. For coastal Tantalite, its main component is tantalite, and Tantalite can be separated by Chloride process. The operation steps of the Chloride process are as follows:

1. Crush the ore into a certain particle size, usually 0.5-1mm.

2. Place the ore in a chlorination furnace for chlorination. The working principle of chlorination is to use chlorine gas to chlorinate tantalum in the ore into tantalate.

3. Hydrolyze the chlorinated ore, and the working principle of hydrolysis is to use water to reduce tantalate to tantalum metal.

4. Extract and process the reduced tantalum to obtain tantalum iron ore.

In a word, there are many methods for selecting coastal Tantalite, and each method has its own application. In practical operation, it is necessary to select based on the composition, particle size, density, magnetism and other characteristics of the ore to achieve the best beneficiation effect.
