Tin ore tailings refer to the waste residue generated during the tin ore beneficiation process, which contains a certain amount of useful minerals that need to be re beneficiated to improve the mineral grade and recovery rate. This article will introduce several common methods of tin ore tailings gravity separation, hoping to be helpful to relevant practitioners.
1. Re-selection process flow
The process flow of tin ore tailings gravity separation mainly includes steps such as grinding, roughing, sweeping, and selection. Among them, grinding is to crush and grind the raw ore to make it reach the Granularity suitable for beneficiation; Coarse separation is the process of removing most of the waste residue from the finely ground ore through methods such as gravity separation or flotation; Sweeping is the further separation of the roughened ore to remove impurities; Selection is the final beneficiation treatment of the scanned ore to improve the grade and recovery rate of the mineral.
2、 Reselection method
1. Gravity sorting method
Gravity separation method is a method of separating minerals by utilizing their different settling velocities under the action of gravity. This method is suitable for minerals with large particles and large density differences. In the re selection of tin ore tailings, a gravity separator can be used to separate tin containing minerals from waste residue.
2. Flotation method
Flotation method is a method of separating minerals and adsorbents by utilizing their differences in hydrophilicity and hydrophobicity in water. This method is applicable to minerals with small particles and small density difference. In the re selection of tin ore tailings, flotation machines can be used for separation to separate tin containing minerals from waste residue.
3. Magnetic separation method
Magnetic separation method is a method of separating minerals by utilizing their different magnetic properties under the action of a magnetic field. This method is applicable to the beneficiation process of magnetic minerals. In the re selection of tin ore tailings, magnetic separators can be used to separate tin containing minerals from waste residue.
III. Precautions
1. The Granularity and water content of ore shall be strictly controlled in the beneficiation process to ensure the beneficiation effect.
2. During the beneficiation process, attention should be paid to protecting minerals to avoid wear or damage.
3. During the beneficiation process, attention should be paid to safety production and strict adherence to relevant safety regulations and operating procedures.
4、 Summary
Tin ore tailings gravity separation is an important means to improve mineral grade and recovery rate. During the beneficiation process, appropriate gravity separation methods and equipment should be selected based on the properties and requirements of the ore, and various parameters in the beneficiation process should be strictly controlled to ensure the beneficiation effect and safe production.
