Tungsten tailings can indeed be recycled. Tailings refer to the remaining useless substances in the ore beneficiation process, usually containing a certain proportion of useful minerals. White tungsten tailings contain valuable metals such as tungsten, molybdenum, bismuth, as well as non-metallic minerals such as quartz, feldspar, mica, garnet, and fluorite. These minerals can be recycled and utilized through appropriate technological means, thereby improving the comprehensive utilization rate of resources, reducing environmental pollution, and achieving resource recycling.
White tungsten tailings contain various elements, including valuable metals such as tungsten, molybdenum, bismuth, as well as non-metallic minerals such as quartz, calcium iron garnet, pyroxene, feldspar, etc. In addition, studies have also mentioned that the valuable metal WO3 content in scheelite tailings is 0.01%, and the Mo content is 0.005%, while the content of non-metallic minerals is relatively high, accounting for 81.9% of the total mineral content.
For example, studies have shown that effective recovery of scheelite can be achieved through a series of experimental studies. Even under the condition of a sample grade of only 0.30%, the grade of scheelite concentrate can reach 50.16%, with a recovery rate of 70.22%. In addition, there are reports that through cooperation with professional companies, the Yongtong tailings recovery scheelite project is expected to bring nearly 20 million yuan in economic benefits annually. The implementation of this project can not only reduce tailings emissions and improve the mining environment, but also achieve a win-win situation of environmental and economic benefits.
Therefore, the recovery of scheelite tailings not only contributes to the sustainable utilization of resources, but also helps to protect the environment, making it an important work with both economic and social value.
The recovery of scheelite tailings usually requires a series of beneficiation equipment to complete, which will be selected according to the specific beneficiation process flow. Generally speaking, the following types of devices may be required:
Crusher: Used to crush scheelite tailings to a certain particle size for subsequent processing.
Grinding machine: Further grind and crush the material to achieve the required particle size for mineral processing.
Classifier: Grading the particle size of the ground material to ensure that the particle size of the material entering the next process meets the requirements.
Gravity beneficiation equipment: Such as jigs, spiral chutes, etc., used to recover heavy minerals from tailings.
Flotation: If specific minerals need to be recovered through flotation, a flotation machine will be used.
Magnetic separator: For tailings containing magnetic minerals, a magnetic separator may be required for recovery.
Centrifuge: Used for recovering fine-grained minerals from tailings.
Filter: Dehydrate the selected minerals to obtain solid mineral products.
The specific equipment required should be determined based on the actual beneficiation process and tailings properties. For example, the beneficiation equipment provided by Xinhai Mining includes various equipment mentioned above, and they can provide customized beneficiation process design, as well as a complete set of beneficiation equipment and services according to customer needs.
