Gravity concentration technology of Wolframite

Wolframite is an important tungsten ore, which has high tungsten content and low impurities. However, the beneficiation of Wolframite is very difficult because its physical and chemical properties are different from other ores. In order to overcome these problems, people have developed a method called Wolframite gravity concentration technology. This article will introduce the principle, operational steps, and application prospects of this technology.

1、 Principle

Wolframite gravity concentration technology is a physical beneficiation method, which uses the density difference and particle size difference between Wolframite and impurities for separation. Specifically, this technology includes the following steps:

1. Rough separation: after preliminary crushing of Wolframite and impurity mixture, rough separation is carried out by gravity separator. In this process, the density difference between Wolframite and impurities will cause them to settle to different levels respectively. Then, they are separated through a vibrating screen.

2. Intermediate selection: send the Wolframite and impurities separated from the roughing process to the gravity concentrator for intermediate selection. In this process, the particle size difference between Wolframite and impurities will cause them to settle to different levels respectively. Then, they are separated through a vibrating screen.

3. Cleaning: Wolframite and impurities separated in the middle selection process are sent to the gravity separator for cleaning. In this process, the density difference between Wolframite and impurities will be more obvious, so they can be separated better. Then, they are separated through a vibrating screen.

Through these steps, Wolframite and impurities can be effectively separated to obtain high-purity Wolframite.

2、 Operating Steps

The operation steps of Wolframite gravity concentration technology are as follows:

1. Crushing: preliminarily crush the mixture of Wolframite and impurities to make its particle size suitable for rough separation.

2. Rough separation: send the crushed mixture to the gravity concentrator for rough separation to separate Wolframite and impurities.

3. Intermediate separation: Wolframite and impurities separated from the coarse separation process are sent to the gravity concentrator for intermediate separation, and Wolframite and impurities with larger particle size difference are separated.

4. Cleaning: Wolframite and impurities separated in the middle selection process are sent to the gravity concentrator for cleaning, and Wolframite and impurities with greater density difference are separated.

5. Vibration screen separation: The mineral processing products and tailings are separated through the vibration screen.

6. Screening: The beneficiation products are sent to the screening machine for screening to remove residual impurities.

Through the above operation steps, high-purity Wolframite can be obtained.

3、 Application Prospects

The Wolframite gravity concentration technology has broad application prospects, which are mainly reflected in the following aspects:

1. Improve the grade of Wolframite: Wolframite gravity concentration technology can effectively separate Wolframite and impurities, thus improving the grade of Wolframite.

2. Reduction of beneficiation cost: Wolframite gravity concentration technology can reduce manual intervention in beneficiation process and reduce beneficiation cost.

3. Environmental protection: Wolframite gravity concentration technology can reduce the discharge of waste and pollutants in the beneficiation process and protect the environment.

4. Promote the development of tungsten industry: Wolframite gravity concentration technology can improve the grade and output of Wolframite and promote the development of tungsten industry.

In short, Wolframite gravity concentration technology is a very important physical beneficiation method, which can effectively separate Wolframite and impurities, improve the grade and output of Wolframite, reduce beneficiation costs, protect the environment, and promote the development of tungsten industry.
