Fluorite ore has various forms of existence in nature, and different forms of existence have different production line processes for fluorite ore beneficiation. During the beneficiation process, appropriate production line processes for fluorite ore beneficiation should be selected based on the type of fluorite ore, in order to achieve high grade fluorite ore beneficiation to a large extent.
Through the comprehensive utilization of fluorite ore, resource waste can be reduced and the value of fluorite ore can be improved. Therefore, a reasonable fluorite ore beneficiation production line process is needed. Jinqiang conducted research on the mineral composition and characteristics of fluorite ore, and ultimately designed a scientific fluorite ore beneficiation production line and fluorite ore beneficiation equipment. Several methods of fluorite ore production line were introduced, and the application flowchart of fluorite ore production line was provided.
The main type of fluorite ore in China is quartz type. The quartz type fluorite ore is mainly divided into Calcite type, Baryte type and sulfide type fluorite ore type fluorite ore. Therefore, this paper analyzes several fluorite ore dressing production lines of fluorite ore.
1. Calcite fluorite production line:
In the Calcite type fluorite ore, the Calcite content is as high as about 30%, containing a small amount of quartz, and finally forming quartz Calcite type ore.
The difficulty of processing such fluorite ore in the fluorite ore dressing production line lies in that both Calcite and fluorite contain calcium minerals, and the mineral surface has relatively similar physical and chemical properties. In the process of processing and separation, conversion between minerals is easy to occur, never causing the problem of ore grade decline.
In the process of Calcite fluorite ore dressing, the method of adjusting pulp PH value and using chemical substances such as collectors can effectively improve the dressing effect. When the PH value is in the range of 8-9.5, oleic acid is used as the collector to effectively float the two ores. In weak acid medium, Calcite has little floatability, and Calcite can be restrained by combination of water glass, saline water glass or acidified water glass to finally achieve separation.
Beneficiation equipment for Calcite fluorite ore
In the beneficiation process of fluorite ore production line, the PH value of Calcite fluorite ore is adjusted mainly by adjusting the PH value. In the beneficiation process of fluorite ore production line, the fluorite ore beneficiation equipment such as agitation tank, flotation machine and flotation machine should be used. In the beneficiation process of fluorite ore production line, the multi-stage grinding method should be used. In the process of fluorite ore production line, the fluorite ore beneficiation equipment such as crusher, feeder and ball mill should be used, Provide appropriate block size for the flotation process.
1. Baryte fluorite production line:
Baryte type fluorite ore is mainly composed of Baryte and fluorite, of which Baryte content is up to 10-40%, accompanied by Pyrite, Galena, Sphalerite and other sulfide minerals.
The processing difficulty of Baryte fluorite production line lies in the difficulty of processing. In the process of processing, it is difficult to separate Baryte and fluorite due to their similar floatability.
The production line of Baryte type fluorite ore generally adopts a mixed flotation process, which combines reagents to adjust the PH value of pulp, takes oleic acid and water glass as the main raw materials, oleic acid and water glass as the raw materials, and adjusts the concentration of reagents. Finally, after obtaining the mixed concentrate of fluorite ore and Baryte, the flotation method is used to separate Baryte and fluorite, and complete the final beneficiation.

Suggested fluorite ore beneficiation equipment: flotation machine.
3. Sulfide type fluorite production line:
The composition of pyrite type fluorite ore is similar to that of quartz type fluorite ore, but the difference lies in the high content of metal sulfides in this type of fluorite ore. Some fluorite ores contain lead, zinc, etc., which can reach industrial grade. The development of sulfide type fluorite ore should consider its recovery problem.
The sulfur type fluorite ore beneficiation production line generally uses sulfide ore collectors to select metal sulfide minerals, and then floats and recovers fluorite together with fatty acid collectors from various countries. After completing the above operations, the fluorite ore beneficiation production line process for valuable metals and fluorite is completed using leaching and other processes, and fluorite is flotation and recovered together with fatty acid collectors from various countries, achieving comprehensive recovery of high-quality fluorite and fluorite.
Sulfur type fluorite ore beneficiation equipment:
Suggested fluorite ore beneficiation equipment: reagent stirring tank, flotation machine, etc.
