120 TPH Fluorite Processing Plant in Mongolia Achieves 97%+ CaF₂ with Jigging Separation

In October 2024, a complete fluorite processing plant designed and manufactured by FRP was successfully commissioned and put into operation at a mining site in Mongolia. The plant integrates crushing, double-shaft spiral washing, screening, and jigging gravity separation, achieving design throughput while delivering fluorite concentrate grades and recovery rates beyond the client's expectations.

The processing line consists of two main sections: the crushing section (outdoor) and the washing, screening and jigging section (indoor workshop). The crushing stage includes a hopper, feeder, one primary PE jaw crusher and two fine jaw crushers, which reduce the run-of-mine fluorite ore to the required particle size for downstream processing.

Inside the workshop, a double-shaft spiral washer intensively scrubs the ore surface to remove attached clay and impurities. The washed material is then classified by a vibrating screen. Fine particles are sent to the 2LTC 6109 jig concentrator, while coarse particles are treated by the FRT 16-2 jig machine. Finally, the fluorite concentrate and tailings are dewatered by a dewatering screen before stockpiling. The entire system operates continuously, efficiently, and with minimal water consumption.

Why Jigging Separation For Fluorite In Mongolia?

The key decision driver for choosing jigging gravity separation over flotation is the combination of technical and commercial benefits:

• Jigging alone achieves the required concentrate grade and recovery rate, meeting client specifications without additional downstream processes.
• Compared with flotation, jigging significantly reduces capital investment because no flotation cells, reagent systems, or grinding stages are required.
• The operation is simpler, the equipment lineup is compact, and maintenance is straightforward, reducing skilled labor requirements.
• No chemicals or reagents are used, making the process environmentally friendly and reducing tailings treatment risks.
• With no chemical agents involved, environmental permitting can be easier and faster, which is important for projects in sensitive regions.

In this Mongolian project, the customer specifically required a simple, cost-effective, and clean process. Jigging separation met the technical targets while keeping the plant approval process smooth.
