Jig Model and Selection Guide for Tin Ore Beneficiation

Jig separators are important equipment in the tin ore dressing process, mainly used for gravity separating coarse and medium-sized tin ores. Its working principle is to use the pulsation of water flow to separate the ore particles according to density, thereby separating cassiterite from gangue minerals. Jig concentrators can be divided into various models according to the processing capacity, transmission mode, and structural characteristics. This article will introduce in detail the selection recommendations of tin ore dressing jigs and common tin ore dressing jig models, and analyze their applicable scenarios and selection points.

 

Jig Machine Selection Guides For Tin Ore Beneficiation

The model and selection guide of the tin ore beneficiation jig machine (also called jig concentrator, or jig separator) should consider multiple factors to ensure that the equipment can meet the beneficiation needs of tin ore. The following are some suggestions and standards for selection:

1. Tin ore characteristics

Ore type: Understand the type of tin ore, including cassiterite (such as heavy mineral cassiterite, quartz, etc.).

Ore particle size: Determine the particle size distribution of the ore. Usually, the jig machine is suitable for sorting particles larger than 0.5mm.

 

2. Processing capacity

Daily processing capacity: Determine the amount of ore that needs to be processed per hour or day to select the appropriate equipment scale.

Sorting efficiency: Consider the sorting efficiency of the equipment. The goal is usually to recover as much tin ore as possible.

 

3. Technical parameters

Jig frequency and amplitude: Select equipment with appropriate jig frequency and amplitude. The frequency is generally 100-300 times/minute, and the amplitude is adjusted according to the characteristics of the ore.

Tank size: Select the tank width, length, and depth according to the processing capacity and ore characteristics.

 

4. Sorting principle

Choose different types of jigs (such as table jigs, hydraulic jigs, etc.) according to the required sorting effect and processing scale.

 

5. Material and wear resistance of equipment

Wear-resistant materials: The interior of the equipment should be made of wear-resistant materials to adapt to continuous wear and corrosion and extend the service life.

Sealing: Ensure that the equipment is well sealed during operation to prevent slurry leakage and environmental pollution.

 

6. Power supply and power requirements

Confirm the required power and power configuration to ensure that the motor power of the jig can support its normal operation.

 

7. Manufacturer and after-sales service

Choose a manufacturer with a good reputation and check the after-sales service and technical support it provides.

Ask the manufacturer for the technical parameters, performance indicators, and successful cases of the equipment.

 

8. Economic efficiency and return on investment

Consider the investment cost, operating cost, and expected payback time of the equipment.

 

Selection Guide Example

Assuming that your ore has an average particle size of 2mm and a daily processing capacity of 100 tons, you can consider the following types of jigs:

Jig Model A 

• Jig trough width: 1.2 meters
• Jig frequency: 150 times/min
• Daily processing capacity: suitable for 100 tons/day

Jig Model B

• Jig trough length: 3 meters
• Motor power: 15kW
• Suitable for the selection of medium-sized tungsten-tin ores

For specific equipment selection, please refer to the detailed technical information provided by the equipment manufacturer. Depending on different needs, the actual parameters may vary, so it is best to consult with professional mineral processing engineers to obtain more accurate suggestions.

 

 

Classification And Common Models of Jig Separators

 

Jig machines can be divided into the following types according to the transmission mode:

• Mechanical transmission jigs (driven by a cam and eccentric connecting rod mechanism)
• Hydraulic transmission jigs (driven by a hydraulic cylinder, with more flexible adjustment)
• Pneumatic jigs (driven by compressed air, suitable for fine-grained materials)

 

According to the structural form, they can be divided into the following types:

• Diaphragm jigs (using rubber diaphragms to generate pulsating water flow)
• Piston jigs (using piston movement to generate pulsation)
• Non-piston jigs (such as sawtooth wave jigs, using special waveforms to improve sorting efficiency)

 

 

(1) Mechanical Transmission Jig Machine

① LTA series jig machine (single/double chamber diaphragm jig machine)

• Model: LTA55/2, LTA1010/2, LTA1515/2, etc. (The number represents the size of the jig chamber, such as 1010 means 1m×1m)
• Processing capacity: 2~20 t/h (depending on the model)
• Features: simple structure, easy maintenance, suitable for small and medium-sized ore dressing plants.
• Applicable ore: coarse and medium-grained tin ore (0.5~10mm).

• Processing capacity: 10~30 t/h
• Features: trapezoidal jig surface, high sorting efficiency, suitable for processing wide-grade materials.
• Applicable ore: 0.5~12mm tin ore, especially suitable for alluvial tin ore.

 

(2) Hydraulic Drive Jig Machine

• Processing capacity: 5~50 t/h
• Features: hydraulic drive, adjustable stroke, and stroke frequency, high sorting accuracy, suitable for complex ores.
• Applicable ore: fine-grained tin ore (0.2~5mm).

• Medium-fine tin ore (0.2~2mm): JT series
• Fine-grained tin ore (<0.2mm): AM-30 or with centrifugal concentrator

• Mechanical transmission: low cost, simple maintenance, suitable for conventional tin ore.
• Hydraulic transmission: flexible adjustment, high sorting accuracy, suitable for complex ores.
• Pneumatic transmission: suitable for fine-grained materials, but with high energy consumption.

 

Conclusion

The selection of tin ore jigs needs to comprehensively consider the processing capacity, ore particle size, transmission mode, and sorting requirements:

• Coarse-grained tin ore: LTA or 2LTC mechanical jigs are preferred.
• Fine-grained tin ore: JT hydraulic jigs or AM-30 pneumatic jigs are recommended.
• Large-scale concentrators: multiple jigs can be connected in parallel, or large-capacity models (such as JT1570) can be selected.

To improve the recovery rate of tin ore, we must start with model selection to ensure that the jig machine matches the actual production. Reasonable jig machine selection and operation can not only improve the utilization efficiency of ore but also bring better economic benefits to the enterprise. At the same time, it is also a key link in the optimization of the tin ore beneficiation process. It is recommended to communicate in depth with professional mining engineers when selecting models and make the best configuration according to ore characteristics and production needs to achieve the best recovery effect.
