Tungsten ore is an important metal mineral widely used in military, aviation, aerospace and other fields. The extraction and beneficiation of tungsten ore is a complex process that requires multiple experiments and validation to obtain the optimal extraction plan. This article will introduce the steps and methods of beneficiation experiments for tungsten ore, hoping to be helpful to relevant practitioners.
1、 Steps of beneficiation test for tungsten ore
1. Sample preparation
Firstly, a sample of tungsten ore needs to be obtained and ground into powder for subsequent experimental operations. During the sample preparation process, attention should be paid to maintaining the integrity and originality of the sample to ensure the accuracy of the experimental results.
2. Preliminary experiments
The previous experiment is mainly to analyze and test the properties and characteristics of tungsten placer, including Mineralogy, chemical composition, physical properties, etc. Through preliminary experiments, it is possible to have a preliminary understanding of the beneficiation properties and difficulty of tungsten ore, providing basic data for subsequent experiments.
3. Design of experimental plan
Based on the preliminary experimental results and the beneficiation characteristics of tungsten ore, design an experimental plan, including the type and dosage of reagents, operating conditions, and other aspects. The design of the experimental plan needs to consider the feasibility and economy of the experiment, while also fully considering the special properties of tungsten ore to ensure the accuracy and reliability of the experimental results.
4. Experimental Operations
Conduct experimental operations according to the experimental plan, including steps such as reagent addition, stirring, precipitation, and filtration. During the experimental operation process, attention should be paid to controlling the experimental conditions and refining the operation to ensure the accuracy and repeatability of the experimental results.
5. Data processing and analysis
After the experiment, it is necessary to process and analyze the experimental data, including material balance, reagent recovery rate, product grade, and other aspects. Through data processing and analysis, the beneficiation indicators and optimal beneficiation plan of tungsten ore can be obtained.
6. Result evaluation and improvement
Evaluate and improve based on experimental results, including optimization of reagent types and dosage, and adjustment of operating conditions. Through continuous improvement, the beneficiation efficiency and economic benefits of tungsten ore can be improved.
2、 Method for beneficiation test of tungsten ore
1. Reselection method
gravity concentration method is a common method for beneficiation of placer tungsten ores. Its principle is to separate the placer tungsten ores into heavy ores and light ores according to the density difference of minerals. The advantage of gravity separation method is its simplicity and feasibility, which is suitable for the beneficiation of various tungsten ore placers. However, its disadvantages are low beneficiation efficiency and poor product grade.
2. Flotation method
flotation method is another common method for beneficiation of tungsten placer ores. Its principle is to separate tungsten placer ores into flotation foam and bottom mud by using the physical and chemical properties of mineral surface. The advantages of flotation method are high beneficiation efficiency and good product grade, but its disadvantages are high requirements for reagent types and dosage, and complex operating conditions.
