Fluorite, also known as calcium fluoride, is a common halide mineral compound with main component calcium fluoride, which is the major source of fluorine elements in related industries. Fluorite comes from lava. In the process of magma cools, the gas aqueous solution isolated by magma contains many substances consisting largely of fluoride. As way up along the fissures, with temperature coming down as well as pressure, the fluorine ions in the gas aqueous solution combined with those calcium ions in the surrounding rocks, form to calcium fluoride, cool and build up fluorite crystallization. 

Our company has own mines in north America, China, Thailand and Lao PDR. We provide all kinds of fluorite lumps as follows.
