The main source of hydrofluoric acid today is the mineral fluorite, otherwise known as calcium fluoride. This mineral is treated with concentrated sulfuric acid, which produces hydrogen fluoride gas. Furthermore, hydrofluoric acid could also be a byproduct during the production of phosphoric acid from the mineral apatite, which naturally includes fluoride ions and phosphate ions in its chemical makeup.
