Tungsten tin tailings refer to the waste left after extracting tungsten and tin from tungsten and tin mines, which contains a certain amount of valuable metals such as tungsten and tin. Due to the large amount of waste generated during the mining and extraction process of tungsten tin ore, the recycling and utilization of tungsten tin tailings has become an important task. This article will introduce the process flow of tungsten tin tailings gravity separation, to help everyone better understand the recycling and utilization process of tungsten tin tailings.
1、 Properties of tungsten tin tailings
Tungsten tin tailings are a complex mineral that contains various metal elements such as tungsten, tin, copper, lead, zinc, etc. The main components of tungsten tin tailings are quartz, Galena, Pyrite, Stibnite, etc., of which tungsten minerals mainly include Scheelite, Wolframite, etc. The properties of tungsten tin tailings are complex and difficult to extract directly, requiring a series of treatment processes to obtain valuable metals.
2、 Process flow of tungsten tin tailings gravity separation
1. Grinding: the tungsten tin tailings are crushed and ground to make their Granularity meet certain requirements for subsequent beneficiation operations.
2. Mineral processing: The tungsten tin tailings after grinding are subjected to mineral processing, mainly through gravity separation, flotation, and other methods to separate valuable metal elements from them. Gravity separation is the process of separating minerals with different densities through the action of gravity, while flotation is the process of separating valuable metal elements from waste through bubbles.
3. Regrinding: The tungsten tin tailings after beneficiation are finely ground again for better subsequent beneficiation operations.
4. Re selection: The tungsten tin tailings after re grinding are re processed for ore dressing to further improve the recovery rate of metal elements.
5. Cleaning: The tungsten tin tailings after beneficiation are cleaned and treated, mainly by separating minerals with different densities through gravity to further improve the recovery rate of metal elements.
6. Dehydration: Dehydrate the selected tungsten tin tailings for better subsequent processing operations.
7. Refining: Refining the dehydrated tungsten tin tailings to obtain higher purity metal elements.
Through the above process flow, we can recycle valuable metal elements from tungsten tin tailings, achieving the dual goals of resource conservation and environmental protection. Of course, the recycling and utilization of tungsten tin tailings also needs to consider factors such as the economy of the process and environmental sustainability, which requires us to comprehensively consider in practical operations.
