Tin ore flotation+gravity separation+magnetic separation process

Tin ore flotation+gravity separation+magnetic separation process

The tin ore flotation gravity magnetic separation process is a beneficiation method used for tin ore containing iron minerals or other magnetic minerals. The arrangement of this process flow usually depends on the properties of the ore and the requirements of the target product.

Tin ore flotation gravity magnetic separation process flow

1.Raw ore crushing :Crush the tin ore raw ore to a certain particle size to prepare for subsequent grinding and beneficiation.

2.Grinding:Grinding the crushed raw ore to achieve appropriate fineness, providing conditions for gravity and magnetic separation.

3.Gravity beneficiation :

  • Classification:Use a hydraulic classifier to classify the slurry and separate different particle sizes of ore.
  • Jig Sorting:Coarse grade ore is sorted by gravity using a jigger to obtain coarse concentrate products.
  • Shaker sorting:Fine grained ore is subjected to finer gravity sorting through a shaker to obtain a purer cassiterite concentrate.

4.Magnetic Separation:Perform magnetic separation on the crude concentrate or shaking bed concentrate selected by gravity to remove magnetic minerals from it. This is usually done using a wet magnetic separator.

5.Flotation:Flotation is carried out on the concentrate after magnetic separation, using appropriate reagents (such as yellow medicine, black medicine, etc.) to separate cassiterite and other minerals. This step can also be performed before or after magnetic separation, depending on the sensitivity of the flotation agent to magnetic minerals.

6.Concentrate Treatment:The flotation concentrate is processed through concentration, drying, and other processes to obtain the final tin concentrate product.

Technological advantages

  • 1.Efficient Separation:Through gravity beneficiation, cassiterite can be effectively separated from other minerals, especially for coarse-grained minerals. The magnetic separation process can remove magnetic minerals from the ore and further improve the purity of cassiterite. The flotation process can enrich fine-grained tin minerals.
  • 2.Resource recovery:This process can recover a large amount of cassiterite resources and further enrich fine-grained tin minerals through flotation, improving resource utilization efficiency.
  • 3.Improve product quality:By combining gravity beneficiation, magnetic separation, and flotation, high-quality concentrate products can be obtained, which is beneficial for subsequent smelting and processing processes.
  • 4.Flexible Adaptation:According to the different properties of the ore and the target product, the process flow can be flexibly adjusted to achieve the best beneficiation effect.
  • 5.Energy saving and environmental protection:Gravity and magnetic separation processes have relatively low energy consumption, and flotation processes can also achieve energy-saving goals. At the same time, this process reduces the generation of tailings, which is beneficial for environmental protection.
  • The tin ore flotation gravity magnetic separation process is an efficient, energy-saving, and environmentally friendly beneficiation method that can achieve high recovery rates of tin ore resources and the production of high-quality products.

Typical beneficiation plant

Xianghualing Tin Mine Dressing Plant: The deposit is a layered cassiterite sulfide ore deposit, with cassiterite being the main tin bearing mineral, in addition to a small amount of natural tin; Gangue minerals are mainly silicates and carbonates, in addition to a small amount of metal minerals such as magnetite, chalcopyrite, and galena.
