Tungsten tin gravity beneficiation process flow

Tungsten tin is an important metal widely used in fields such as electronics, aerospace, and military. And tungsten tin ore is the main source of tungsten tin, so the ore dressing process is crucial. The tungsten tin gravity beneficiation process is a commonly used beneficiation method. This article will introduce the tungsten tin gravity beneficiation process flow and its operating steps.

1、 Introduction to tungsten tin gravity beneficiation process

The tungsten tin gravity beneficiation process is a method of using gravity beneficiation equipment to separate minerals based on their different settling velocities in the gravity field. This process is applicable to ores with coarse mineral size and large density difference. The commonly used gravity beneficiation equipment includes heavy medium separation, spiral separation machine, vibration beneficiation machine, flotation machine, etc.

1. Ore crushing

Firstly, it is necessary to crush the tungsten tin ore for subsequent beneficiation operations. The crushing method generally adopts jaw crusher, cone crusher, impact crusher, etc.

2. Ore screening

The crushed ore needs to be screened and divided into different levels according to particle size. Commonly used screening equipment includes vibrating screens, cyclones, screening machines, etc.

3. Re selection

heavy medium separation is an important separation method in tungsten tin gravity beneficiation process. Its principle is to use the difference in settling speed of the medium in the gravity field to classify minerals into different density levels. Heavy medium separation equipment generally uses a density of 2.5-3.5g/cm ³ Heavy medium, such as Baryte, heavy quartz, etc.

4. Spiral sorting machine

The spiral separator is a commonly used gravity beneficiation equipment, which uses spiral blades to separate minerals along the spiral axis. Spiral sorting machines can be divided into two types: single spiral sorting machines and double spiral sorting machines.

5. Vibration concentrator

Vibration concentrator is a device that utilizes the difference in settling speed of minerals in a vibration field for sorting. The principle is to separate minerals using centrifugal and inertial forces in the vibration field. Vibration concentrators can be divided into two types: linear and circular.

6. Flotation machine

A flotation machine is a device that utilizes the difference in affinity between minerals and bubbles for sorting. The principle is to inject a certain amount of reagents and bubbles into the flotation cell to form foam between minerals and bubbles, so as to achieve separation. Flotation machines are divided into two types: mechanical flotation machines and air flotation machines.

3、 Conclusion

The tungsten tin gravity beneficiation process is a commonly used beneficiation method, with simple and easy to master operating steps. In practical applications, it is necessary to select appropriate beneficiation processes and equipment based on the characteristics and requirements of the ore, in order to achieve the best beneficiation effect.
