A client from Guizhou Province, China approached FRP with the intention of building a 100 TPH barite beneficiation production line. At the time, the client had no prior experience in mineral processing and limited understanding of barite ore characteristics or gravity separation technology.
The raw material presented a significant technical challenge: grey barite ore with fine disseminated grain size and complex physical properties. Such ore is highly sensitive to crushing and classification. If gravity separation is not precisely controlled, fine barite particles are easily lost, leading to reduced concentrate quality and poor resource utilization.
To minimize investment risk, the client decided to conduct side-by-side comparative jigging tests, selecting two jigging machine suppliers, including FRP, to evaluate performance under identical operating conditions.
Under the same feed conditions and identical recovery rates, the comparative testing revealed a decisive difference in concentrate quality:
Concentrate specific gravity improved from SG 3.8 to SG 4.2.
Concentrate specific gravity improved from SG 3.8 to SG 4.3.
While recovery rates were equivalent, the 0.1 SG improvement achieved by the FRP solution represented a fundamental advantage. In barite beneficiation, this difference directly affects market acceptance and selling price.
Based on this clearly measurable and repeatable result, the client selected FRP as the process and equipment partner for the full-scale project.
Taking into account the fine grain size, high friability, and feed size sensitivity of grey barite, FRP designed the following beneficiation process:
Coarse Crushing → Fine Crushing → Jigging Recovery → Dewatering → Drying → Grinding
Main sections of the grey barite beneficiation production line.
Grey barite is highly brittle and prone to over-grinding. To prevent excessive fines generation, FRP deliberately selected a roller crusher instead of impact crushers or high-speed crushing equipment.
The roller crusher operates on a compression-shear crushing principle, which allows mineral liberation while minimizing the generation of fine powder.
This approach effectively preserves the particle size range suitable for jigging separation and reduces barite loss during the crushing stage.
For the fine-grained and gravity-sensitive nature of the ore, FRP configured a 2LTC6109/8T jigging machine as the core separation unit.
The 6109 jigging machine adopts a four-row configuration with a total of eight jigging chambers. Each row is equipped with an independent drive system, and both stroke and frequency can be adjusted independently.
The value of this configuration lies in higher process controllability:
For grey barite ore with fine grain size and high sensitivity to separation conditions, this level of controllability is essential for reducing fine particle loss, improving concentrate specific gravity, and maintaining long-term stable operation.
In this project, the final 0.1 SG advantage over the competing solution was not an accidental outcome. It was the combined result of process control capability and the separation precision of the 6109 jigging machine.
Since commissioning, the barite beneficiation plant has operated stably and achieved the tested results. The system demonstrates strong industrial adaptability and is well suited to continuous production.
Ease of operation and maintenance is especially important for a first-time mineral processing operator with no prior experience.
Lower power consumption and reduced wear part replacement compared with traditional high-speed equipment.
Overall low operating cost while reliably producing premium barite concentrate with a specific gravity of SG 4.3+.
The client expressed high satisfaction with FRP’s process design capability, equipment performance, and engineering support.
If you are processing grey barite or other fine-grained, gravity-sensitive minerals, FRP’s experience provides a proven reference.
