Click to add WeChatTailings are waste produced after mineral processing. In the early days, due to limited mining technology and lagging mineral processing equipment, some useful minerals remained in the tailings. In mines, if these minerals are effectively recovered, it is an effective way to improve mineral utilization, and tungsten ores are no exception. There are currently many technological methods for re-selecting tungsten tailings, such as flotation, gravity separation, magnetic separation, etc., which are all effective separation methods. However, how to choose depends on the composition of the ore and the tailings. Depends on the characteristics. Let’s take a look at these tungsten tailings reselection methods.
The flotation method can effectively recover the tailings When flotating tungsten, we use Flotation machine and Pharmaceutical stirring system. To encourage bubbles to attach to valuable tungsten minerals, causing them to float to the surface, while allowing unwanted gangue minerals or impurities to sink. Flotation cells facilitate the separation process by providing a controlled environment that facilitates the selective attachment of air bubbles to target minerals. This method is crucial for recovering valuable tungsten minerals from tailings, aiding resource utilization and reducing environmental impact in tungsten ore beneficiation operations.
Gravity separation and reselection of tungsten tailings Mining is one of the methods, which can use such methods asShaker, Jig, Spiral Chute andCentrifugeand other equipment are used for re-selection. When sorting tungsten tailings by gravity separation method, the density difference between it and gangue minerals is fully utilized. The tailings are fed into the equipment, where a stratification effect is produced through controlled shaking or centrifugal force, so that the heavier tungsten tailings are separated. The tungsten minerals precipitate and are collected, while the lighter magazine minerals are washed away. This gravity-based method provides an efficient and cost-effective way to recover valuable tungsten minerals from tailings, helping to both conserve resources and protect the environment in tungsten mining operations.
Magnetic separation method for re-selection of tungsten For tailings, magnetic separation is mostly used to separate magnetic minerals in the tailings. During mineral processing, the tungsten tailings will be affected by the magnetic field, causing the magnetic tungsten minerals to be adsorbed to the magnets and then separated from the non-magnetic minerals. Commonly used equipment for this method include Magnetic drum, magnetic separator or circular flux magnetic separator, etc.
Wet re-selection is a kind of chemical beneficiation method. The tailings are treated with acids or other chemicals to dissolve them. and recycled tungsten. When using hydrometallurgy to treat tailings, special equipment such as leaching tanks and solvent extraction devices are required for effective treatment. The tailings are dissolved with acid or other solvents to extract tungsten minerals.
The above are the four processing methods for re-selecting tungsten tailings. When selecting the process, you should first conduct a mineral processing test analysis to determine the composition of the ore, and then design a suitable tungsten system according to the actual situationTailings re-selection method to obtain a better return on investment.
