Tungsten is an important metal material widely used in the manufacturing of high-speed steel, alloy steel, hard alloys, electronic devices, and other fields. As the main source of tungsten, the quality and output of tungsten are directly affected by the beneficiation process of tungsten ore. This article will introduce an efficient tungsten ore selection process to help miners improve the recovery rate and quality of tungsten.
1、 Preparation before selecting tungsten ore
Before processing tungsten ore, it is necessary to conduct preliminary treatment of the ore in order to better beneficiate it. Firstly, it is necessary to treat the ore with crushed stones, grinding, etc., in order to break it into appropriate particle sizes. Secondly, it is necessary to pre-treat the ore before flotation, including desliming, iron removal, etc., in order to reduce the interference of impurities in the beneficiation process.
II. Flotation Process of Tungsten Ores
1. Grinding
Send the preliminarily processed ore into a ball mill for grinding, breaking it into smaller particles. The purpose of grinding is to increase the surface area of the ore and facilitate the adsorption of flotation agents.
2. Selection of flotation agents
Flotation agents are the key to flotation, and their selection will directly affect the beneficiation effect. The commonly used flotation agents currently include xanthate, acetone, etc. When selecting flotation agents, it is necessary to consider factors such as the properties of the ore and the adsorption performance of the flotation agent.
3. Preparation of mineral slurry
Mix the ground ore with the flotation agent to make a slurry. The ratio of ore slurry needs to be adjusted based on the properties of the ore and the characteristics of the flotation agent in order to achieve the best beneficiation effect.
4. Selection of flotation machine
Flotation machines are the core equipment for flotation, with a wide variety of types, including mechanical flotation machines, air flotation separators, centrifugal flotation machines, etc. When selecting a flotation machine, it is necessary to consider factors such as the properties of the ore, the concentration of the slurry, and the type of flotation agent.
5. Control of flotation process
During the flotation process, it is necessary to adjust the various parameters of the flotation machine in order to achieve the best beneficiation effect. The commonly used control parameters include the feed rate of the flotation machine, the amount of flotation agent input, and the stirring speed.
3、 Treatment after selecting tungsten ore
After processing tungsten ore, subsequent treatment of the beneficiation products is also necessary to improve the recovery rate and quality of tungsten. Common processing methods include gravity separation, magnetic separation, chemical separation, etc.
In summary, the tungsten ore beneficiation process is a complex process that requires miners to comprehensively consider factors such as the properties of the ore and the characteristics of flotation agents in order to achieve the best beneficiation effect. Through the introduction of this article, it is believed that readers have a deeper understanding of the tungsten ore selection process, hoping to help miners improve the recovery rate and quality of tungsten.
