Hydrofluoric acid (HF) is a building block for almost all fluorine compounds. HF can be produced directly from the mineral Fluorite, but also as a by-product of phosphoric acid.
HF is primarily used in oil refining, as well as steel and aluminum production making oil&gas and construction key industries.
