The energy and material consumption per metric tonne of AHF produced in the fluorspar process is shown in Table 2. However, today, 95% of available fluorspar is used to make HF (British Geological Survey, n.d.), and only 5 plants produce AHF from H 2 SiF 6. As a result, the fluorspar process is the primary method for producing HF.
