Fluorite, or calcium fluoride (CaF. 2), also known as fluorspar in the mining industry, is a glassy mineral con-sisting of calcium (51%) and fluorine (49%). Along with the lead and zinc ores, great quantities of fluorite came out of the mines. Initially the fluorite was discarded because there were no known uses for it. Commercial fluorite ...

Fluoride is liberated from the mineral by the action of concentrated sulfuric acid: CaF2(solid) + H2SO4(liq) ⇒ CaSO4 (solid) + 2HF (gas) The resulting HF is converted into fluorine, fluorocarbons, and diverse fluoride materials. As of the late 1990s, 5 billion kilograms were mined annually.

A new study from a team of European based researchers has revealed UHPFRC could be produced using sand waste from fluoride mining operations. The study team said they were able to reach two main conclusions. First, they found the inclusion of sand wastes lead to a more continuous distribution of particle size, which reduced water requirements.

The production of fluorapatite can be done in a three-step process in addition to mining from the natural sources. At the first step, we need to generate calcium phosphate by combining calcium and phosphate salts. The pH is neutral here. Then, this material is reacted with fluoride sources to get the mineral.

1.2 What are fluorides used for in industry? Hydrogen fluoride (HF) is a colourless, pungent liquid or gas that is highly soluble in organic solvents and in water, in which it forms hydrofluoric acid. Calcium fluoride (CaF 2) is a colourless solid that is relatively insoluble in water and dilute acids and bases.

Fluoride contamination is a major problem in wastewater treatment. Metaettringite (which has previously shown enhanced anion adsorption) was investigated as a possible adsorbent to remove fluoride from low-concentration solution (25 mg-F/L). The fluoride removal properties of ettringite and metaettringite were first compared at pH 10, and metaettringite was found to be more effective.
