The method of mineral processing in tin mines is determined by its own characteristics. Since the density of cassiterite is greater than the density of symbiotic minerals, the traditional beneficiation process of tin ore is gravity beneficiation. At the same time, due to the presence of other useful metal minerals and vermiculite in the cassite polymetallic sulphide ore, there are auxiliary processes such as flotation, magnetic separation and electrification when sorting the tin ore.


The tin ore crusing plant is roughly divided into four parts: crushing, grinding, flotation and drying. The stages are properly connected, the equipment configuration is reasonable, the whole process is smoother, and the operation is also more convenient.

1. The crushing stage
The nature of the ore ore is relatively simple, and only a one-step crushing of the jaw crusher can achieve good results. After crushing, the tin ore has uniform particle size, beautiful grain shape and no over-grinding. It provides high-quality raw materials for the next step, reduces the load of grinding equipment, and promotes the quality of tin concentrate.
2. Grinding stage
In the tin ore grinding stage, the crushed material is uniformly sent into the ball mill and ground to a powder shape, in order to achieve sufficient dissociation of tin minerals and other minerals. At this stage, the spiral classifier is required to reasonably classify the material after grinding, and the qualified materials satisfying the conditions can enter the next stage; otherwise, it will be sent back to the crusher to continue to be crushed, so that the cycle is repeated. The energy consumption of the whole grinding section is relatively low and the operation effect is good.
3. Flotation stage
Flotation is the key link of the whole tin ore dressing. It uses the special flotation machine of tin mine designed by Red Star Machine. It has higher sorting precision, more convenient operation, less waste of medicine and no environmental pollution. After grinding, the tin ore powder first enters the mixing tank and is fully stirred into a slurry, and then sent to the flotation machine, and the corresponding flotation agent is added to fully react to obtain the tin concentrate.
4, drying stage
The tin concentrate after flotation will contain a lot of water, which needs to be dehydrated and dried by a dryer to better improve the tin concentrate grade. The use of our company's dryer equipment will save fuel, improve drying efficiency and effectiveness, and the drying process can eliminate all dust and noise pollution, creating an efficient and environmentally friendly production environment.

Characteristics of tin ore crusing plant:
1. The whole production line is cheap, the space layout is compact, and the investment cost is effectively reduced;
2. The operation is more stable, the noise is less, and the pollution is less;
3. Low failure rate, large processing capacity, high degree of automation, and convenient operation;
4. The flotation effect is good, the grade of tin concentrate is increased by 30%, and the comprehensive utilization of resources is fully realized.
