A mining client in Guizhou Province planned to build a 100 TPH barite beneficiation production line. At the start of the project, the client had no prior experience in mineral processing and lacked practical understanding of barite ore characteristics and gravity separation technology.
To reduce investment risks, the client visited two equipment supplier factories (including FRP) to conduct mineral processing tests, evaluating gravity beneficiation performance under identical feed and operating conditions.
Under identical feed conditions and equivalent recovery rates, testing at the two supplier facilities demonstrated a clear gap in concentrate specific gravity:
Concentrate specific gravity increased from SG 3.8 to SG 4.2.
Concentrate specific gravity increased from SG 3.8 to SG 4.3.
Based on this clear and repeatable test data, the client ultimately selected FRP as the process and core equipment partner for the 100 TPH beneficiation plant.
Based on the physical characteristics of grey barite ore, FRP's engineering team designed the following targeted process flowsheet:
Primary Crushing → Fine Crushing (Roller Crusher) → Jigging Separation → Dewatering → Drying → Grinding
Main workshop and equipment layout of the 100 TPH grey barite beneficiation line.
Grey barite has high brittleness. If conventional impact crushing equipment is used, its high line-speed impact will cause severe over-grinding problems, leading to a sharp decline in gravity recovery.
Based on the principle of "moderate liberation", FRP selected a double roller crusher in the fine crushing stage, changing "impact" into "compression and shear". This transition not only significantly reduces fine powder production, but more importantly, precisely controls the crushed product particle size within the high-efficiency separation range of the jigging machine. This fundamentally solves the conflict between "liberation and over-crinding", creating ideal feed conditions for gravity separation.
Targeting the fine-grained dissemination and gravity-sensitive characteristics of this ore, FRP selected the four-row, eight-chamber 2LTC6109/8T trapezoidal jigging machine as the core separation equipment. Its core advantages are reflected in three aspects:
Since the production line was officially commissioned, the plant has operated with high stability, continuously producing high-quality concentrate consistent with the testing phase:
For a client stepping into mineral processing for the first time without prior experience, the entire system is intuitive to operate and easy to maintain.
Compared with high-speed impact crushing equipment, the double roller crusher and trapezoidal jigging unit have lower power consumption and significantly reduced wear-part replacement frequency.
Maintains extremely low processing costs per ton while reliably producing premium barite concentrate with a specific gravity of SG 4.3+.
The client expressed high satisfaction with FRP's process design capabilities, actual equipment performance, and comprehensive engineering support.
