Here’s a typical fluorite processing plant process flow:

• Crushing:
  • Reducing the size of raw fluorite ore to a manageable size for subsequent processing.
  • Equipment used: crushers, cone crushers, impact crushers.
• Grinding:
  • Further reducing the particle size of the crushed ore to liberate the valuable fluorite mineral from the gangue minerals.
  • Equipment used: Ball mills, rod mills.
• Classification:
  • Separating the ground ore into different size fractions to optimize the subsequent separation processes.
  • Equipment used: Hydrocyclones, classifiers, screens.
• Beneficiation:
  • Separating the fluorite mineral from the gangue minerals using various techniques, such as flotation, gravity separation, or magnetic separation.
  • Equipment used: Flotation machines, shaking tables, magnetic separators.
• Dewatering:
  • Removing excess water from the fluorite concentrate to improve its handling and storage properties.
  • Equipment used: Thickeners, filters, centrifuges.
• Drying:
  • Further reducing the moisture content of the fluorite concentrate to meet the specifications of the end users.
  • Equipment used: Rotary dryers, fluidized bed dryers.

Summary of Fluorite Ore Flotation Process

Uses

The majority of the United States’ annual consumption of fluorspar is for the production of hydrofluoric acid (HF) and aluminum fluoride (AlF3). HF is a key ingredient for the production of all organic and non-organic chemicals that contain the element fluorine. It is also used in the manufacture of uranium. AlF3 is used in the production of aluminum.

The remainder of fluorspar consumption is as a flux in making steel, glass, enamel, and other products. Flux is a substance that lowers the melting temperature of a material.
