Tungsten sand beneficiation process flow

Tungsten sand is an important metal mineral with high melting point, high hardness, and high density, widely used in aviation, aerospace, military and other fields. The beneficiation process of tungsten sand refers to the process of extracting tungsten from tungsten containing ores through a series of physical and chemical treatments. This article will provide a detailed introduction to the tungsten sand beneficiation process and its operating steps.

I. Tungsten sand beneficiation process flow

The tungsten sand beneficiation process usually includes the following steps:

1. Crushing: The raw ore is preliminarily crushed by a crusher to achieve a certain particle size requirement.

2. Grinding: The preliminarily crushed ore is sent to a ball mill for further grinding to make its particle size finer.

3. Flotation: immerse the milled ore in the flotation cell, add reagents, make the tungsten ore and foam rise to the cell surface together, and then separate the foam and minerals through the scraper.

4. Grinding and selection: The flotation tungsten ore is fed into a grinding and selection machine for further grinding to obtain higher grades.

5. Selection: The tungsten ore after grinding is sent to the selection machine for fine separation to obtain high-grade tungsten sand.

2、 Operating Steps

1. Crushing operation: Feed the raw ore into the crusher and select different crusher models and specifications based on the hardness and particle size of the ore. The crushed ore should meet a certain particle size requirement, usually around 10-20mm.

2. Grinding operation: The preliminarily crushed ore is sent to a ball mill for grinding, and different ball mill models and specifications are selected based on the hardness and particle size of the ore. The ore after grinding should meet a certain fineness requirement, usually around 0.074mm.

3. Flotation operation: Immerse the finely ground ore into the flotation tank, add reagents, and select different types and amounts of reagents based on the characteristics of the ore and the beneficiation process. The tungsten ore after flotation should meet a certain grade requirement, usually around 0.5% -2%.

4. Grinding and selection operation: The flotation tungsten ore is fed into a grinding and selection machine for further grinding, and different grinding and selection machine models and specifications are selected based on the grade and fineness requirements of the ore. The ore after grinding should meet higher grade requirements, usually around 5% -10%.

5. Selection operation: The tungsten ore after grinding is sent to the selection machine for fine separation, and different selection machine models and specifications are selected based on the grade and separation effect of the ore. The selected tungsten ore should meet higher grade requirements, usually around 60% -70%.

3、 Summary

The beneficiation process of tungsten sand is a complex engineering process that requires multiple physical and chemical treatments in order to ultimately obtain high-grade tungsten sand. During the operation process, different equipment and reagents need to be selected based on the characteristics of the ore and the beneficiation process to achieve the best beneficiation effect. At the same time, it is also necessary to ensure the normal operation and maintenance of equipment to ensure production efficiency and product quality.
