The dry separation process of tin ore is an important method of tin ore beneficiation, whose main function is to remove impurities from tin ore through physical and chemical methods, improve the grade of tin ore, and thus meet the requirements of industrial production. This article will provide a detailed introduction to the operating steps and precautions of the tin ore dry separation process.
1、 Operation steps of tin ore dry separation process
1. Raw material screening: Screen the raw materials to remove impurities and ensure their purity.
2. Crushing: Crushing raw materials to achieve a certain particle size requirement.
3. Magnetic separation: Magnetic separation is performed on the crushed raw materials to remove any magnetic substances.
4. Re selection: The raw materials after magnetic separation are re selected to remove heavy impurities.
5. Flotation: Flotation is performed on the re selected raw materials to remove light impurities.
6. Re magnetic separation: The raw materials after flotation are re magnetic separated to remove magnetic substances.
7. Re selection: The raw materials after re magnetic separation are re selected to remove heavy impurities.
8. Screening: The re selected raw materials are screened to separate tin ore with different particle sizes.
9. Drying: Dry the screened tin ore to a certain degree of dryness.

II. Precautions for Tin Ore Dry Separation Process
1. Selection of raw materials: Choosing high-quality and high-purity raw materials can improve the dry separation effect.
2. Equipment selection: Choosing equipment with good performance and easy operation can improve the efficiency of dry selection.
3. Standardization of operation: During operation, standard operating procedures should be followed to avoid affecting the dry selection effect due to non-standard operation.
4. Safety production: Pay attention to safety during operation to avoid accidents.
5. Environmental protection: Pay attention to environmental protection during operation to avoid polluting the environment.
III. Conclusion
Tin ore dry separation process is an important tin ore beneficiation method, and its operating steps and precautions are crucial for improving the dry separation effect. In practical operation, attention should be paid to selecting good raw materials, equipment, and standardized operations to ensure dry separation efficiency and safe production, and pay attention to environmental protection, making contributions to the tin mining industry production.
