Tungsten tin ore is a common metal ore that contains precious metals such as tungsten and tin. In industrial production, the application of tungsten tin ore is very extensive, therefore, the ore beneficiation process has become very important. In this article, we will provide a detailed introduction to the beneficiation process of tungsten tin ore.
1、 Mineralogy characteristics of wolframite
Tungsten tin ore is mainly composed of quartz, Galena, cassiterite, Scheelite, Wolframite and other minerals. Among them, Scheelite and Wolframite are the main minerals of tungsten ore, and cassiterite is the main mineral of tin. Quartz and Galena are associated minerals in wolframite.
2、 The beneficiation process of tungsten tin ore
The beneficiation process of tungsten tin ore mainly includes the following steps:
1. Rough selection
After crushing and screening, tungsten tin ore enters the rough selection process. In the rough selection process, the ore is gravity separated into tungsten concentrate, tin concentrate, and tailings through a gravity separator. Among them, tungsten concentrate and tin concentrate are the main products of this beneficiation.
2. Successful selection
After rough selection, metals such as tungsten and tin in tungsten tin ore have been preliminarily separated. Next, further separation of tungsten and tin is needed. In the selection process, tungsten concentrate and tin concentrate are separated by flotation using a flotation machine.
After selection, tungsten and tin have been separated. Next, further purification of tungsten and tin is needed. In the selection process, tungsten and tin concentrates are re selected using a gravity separator to remove impurities and improve the grade of tungsten and tin.
4. Tailings treatment
During the beneficiation process of tungsten tin ore, a large amount of tailings will be generated. These tailings contain certain metals such as tungsten and tin, which need to be recycled. In the tailings treatment process, methods such as gravity separation and flotation are used to treat the tailings, and the tungsten, tin, and other metals in the tailings are recycled and utilized.
The beneficiation process of tungsten tin ore includes four stages: rough beneficiation, intermediate beneficiation, beneficiation, and tailings treatment. Through these processes, metals such as tungsten and tin can be separated from the ore, improving its grade and meeting the requirements of industrial production. The beneficiation process of tungsten tin ore should be noted that different minerals have different beneficiation characteristics and need to be selected based on actual conditions to achieve the best beneficiation effect.
