Note : "-"in the form means no rules about content. If customer have special requirements, both sides can decide through consultation.
Physical properties: It has glaucous fluorescence under Uv ray. Vitreous burnish. Moss hardness is 4. Specific gravity is 3.18. Basically originate in hydrothermal lode. Can be green, white, yellow, blue, purple, etc. Pure fluorite originate in geode of fluorite pulse and looks colorless and transparent.
Applications: It is the main raw material of making hydrofluoric acid. It is also used in the enamel manufacturing, optical glass, glass fiber, laser generator, and coating.
Packing: In 50kg PP bags, Lined with high-pressure plastic film, or according to contract's requirements，lump ore can be packed in 1000kg pp bags or in bulk.
