The properties of blue fluorite and the fluorite process

What is blue fluorite?

Blue fluorite, also known as fluorite, is a gem-grade halide mineral. Its chemical composition is calcium fluorosilicate, which is an important raw material for extracting fluorine.

How blue fluorite is formed

Magnesium fluoride and calcium fluoride form blue fluorite under high temperature and high pressure conditions. Generally, it is formed in hydrothermal veins. Blue fluorite is formed by filling and precipitation of fluoride dissolved in hot water. Its formation process is mainly affected by factors such as pressure, temperature, and solution pH. Sometimes, blue fluorite may also exist in alternating veins and carbonate rocks.

Properties of blue fluorite

The chemical formula of blue fluorite is CaF2, and its main component is calcium fluoride. In addition, it contains a small amount of silicon, magnesium, aluminum and other elements.

The Mohs hardness of blue fluorite is between 4-5, the density is about 3.3g/cm³, the specific gravity is about 3.2, the refractive index is about 1.438, the glass luster, the crystals are octahedral, cubic, etc., in granular or blocky form.

Uses of Fluorite

Jewelry and decorations: Blue fluorite has moderate hardness, beauty and durability, and can be finely processed into various shapes and patterns, while maintaining its natural luster and beauty. It is often processed into various jewelry or pendants. Blue fluorite can also be used for interior decoration and artwork production, such as decorative materials such as walls, floors, and columns, and can also be carved into various artworks, accessories, and crafts. Due to the soft and quiet atmosphere and noble and precious status of high-end blue fluorite itself, it often appears in high-end indoor spaces and important places.

Scientific research: Blue fluorite has birefringence and fluorescence properties, so it has a wide range of uses in the scientific field. For example, it is used to study the properties of light, electricity, and magnetism, and can also be used to study various astronomy and geophysics.

Therapeutic uses: Blue fluorite has the ability to balance the energy of the human body, and can be used for treatment, health, and emotional relief, so it is made into various healing equipment and products.

Fluorite color classification

It can be divided into green fluorite, purple fluorite, blue fluorite, yellow fluorite, colorless fluorite, etc.

Appearance difference between blue fluorite and kyanite

Blue fluorite is usually light blue or green, and looks like translucent candy, and sometimes appears in short lines of russet or purple.

The color of kyanite may vary depending on the copper or other ingredients it contains. Usually, kyanite is blue or brown, with a relatively regular crystal shape, and a bright light appears when it is seen through kyanite.

Fluorite crushing equipment and crushing process

Fluorite crushing equipment

Common fluorite crushing equipment on the market includes jaw crusher, Cone Crusher, and impact crusher. Different crushing equipment is required for different stages of crushing. In addition to crushing equipment, there are also feeders, conveyors, vibrating screens and other equipment.

Fluorite crushing process

The fluorite material is uniformly sent to the jaw crusher by the vibrating feeder for coarse crushing. The coarsely crushed stone is then sent to the cone crusher by the belt conveyor for medium crushing. The medium crushed material is sent to the vibrating screen by the conveyor for screening. The material that does not meet the discharge requirements is sent to the impact crusher for fine crushing, and the material that meets the requirements will be sent to the silo. If the user has higher requirements, the stone can be cleaned with a sand washing machine, and then sent to the silo after removing the debris.
