Access to fluorochemicals directly from fluorspar [PDF]
Communications Chemistry, 2023 Fluorochemicals have a wide range of applications in industry, but accessing these relies on the energy intensive conversion of acid-grade fluorspar (CaF2) to toxic hydrogen fluoride (HF) gas, which is in turn used for the downstream production of ...

Influence of fluorspar replacement in desulfurizing mixtures and variation of process parameters on the hot metal desulfurization efficiency [PDF]
REM: International Engineering Journal, 2023 Fluorspar (CaF2) is the most used flux in hot metal desulfurizing mixtures. However, its use can cause refractory wear and environmental contamination, prompting research efforts to develop alternative desulfurizing mixtures.

Development of a new parameter for predicting hot metal desulfurization efficiency
REM: International Engineering Journal, 2021 Over the last decades, the capability of a desulfurizing mixture to remove sulfur has been widely studied. The hot metal desulfurization efficiency represents the percentage of sulfur removed from the bath and the development of parameters that predict ...
