Scheelite gravity concentration method

Scheelite gravity concentration method

Scheelite is an important metal ore, which is widely used in electronics, aviation, aerospace and other fields. However, in the process of mining and beneficiation of Scheelite, there are often some problems that are difficult to deal with, such as low grade and difficult beneficiation. In order to solve these problems, scientists continue to explore and research, and finally found some effective Scheelite gravity concentration methods. This article will introduce some common methods of Scheelite gravity concentration, hoping to be helpful to your work and study.

1、 Preparation before re selection

Before gravity concentration of Scheelite, some preparations are needed to ensure the maximum beneficiation effect. Specifically, it includes the following aspects:

1. Crushing and grinding of ore

Crushing and grinding of ore is the pre work of Scheelite gravity concentration, which aims to crush the ore into suitable particle size for subsequent beneficiation operations. Generally speaking, methods such as mechanical crushing and ball mill grinding can be used for ore crushing and grinding.

2. Classification of ores

The classification of ore refers to dividing it into different levels based on its particle size for subsequent beneficiation operations. Generally speaking, ore classification can be achieved through methods such as screening and hydraulic classification.

3. Flotation of ores

Flotation of ores refers to the process of separating useful minerals from waste rocks using physical or chemical methods. Generally speaking, methods such as air flotation and oil flotation can be used for ore flotation.

2、 Common gravity concentration methods of Scheelite

1. Gravity beneficiation method

Gravity beneficiation method refers to the method of separating useful minerals from waste rocks in ore using physical and mechanical principles. Generally speaking, gravity beneficiation can adopt methods such as heavy medium beneficiation, centrifugal beneficiation, and gravity flotation. Among them, heavy medium beneficiation refers to the method of separating ores using media of different densities, centrifugal beneficiation refers to the method of separating ores using centrifugal force, and gravity flotation refers to the method of separating ores using gravity.

2. Flotation beneficiation method

Flotation beneficiation method refers to the use of physical or chemical methods to separate useful minerals from waste rocks in ores. Generally speaking, flotation beneficiation methods can use methods such as air flotation, oil flotation, and chemical flotation. Among them, air flotation refers to the method of using bubbles to separate useful minerals from waste rocks in ores, oil flotation refers to the method of using oil droplets to separate useful minerals from waste rocks in ores, and chemical flotation refers to the method of using chemical agents to separate useful minerals from waste rocks in ores.

3. Magnetic separation beneficiation method

The magnetic separation beneficiation method refers to the method of using magnetism to separate useful minerals from waste rocks in ores. Generally speaking, the magnetic separation method can adopt methods such as weak magnetic separation, medium magnetic separation, and strong magnetic separation. Among them, weak magnetic separation refers to the method of using a weak magnetic field to separate useful minerals from waste rock in an ore, medium magnetic separation refers to the method of using a medium intensity magnetic field to separate useful minerals from waste rock in an ore, and strong magnetic separation refers to the method of using a strong magnetic field to separate useful minerals from waste rock in an ore.

3、 Summary

Through the introduction of the above-mentioned Scheelite gravity concentration methods, we can see that each method has its unique advantages and scope of application. Therefore, in practical work, the most suitable gravity separation method should be selected based on the specific situation to achieve the best beneficiation effect.

Before gravity concentration of Scheelite, some preparations need to be carried out, such as ore crushing and grinding, ore classification and ore flotation. In actual operation, it is also necessary to pay attention to some details, such as operating specifications, equipment maintenance, etc. Only when these preparations and precautions are done well, can Scheelite gravity separation be carried out smoothly and good beneficiation results be achieved.

In a word, Scheelite gravity concentration is a complex work, which requires scientists to constantly explore and study in order to find more effective beneficiation methods. It is believed that in the near future, we will be able to develop a more efficient and environmentally friendly Scheelite gravity separation method and make greater contributions to human science and technology.
