AP-42, CH 8.7: Hydorfluoric Acid U.S. Environmental Protection

Hydrofluoric acid is manufactured by the reaction of acid-grade fluorspar (CaF2) with sulfuric acid (H2SO4) as shown below: CaF2 H2SO4 → CaSO4 2HF A typical HF plant is shown schematically in Figure 8.7-1. The endothermic reaction requires 30 to 60 minutes in horizontal rotary kilns externally heated to 200 to 250°C (390 to 480°F). DryFluorspar Flotation. The lead and fluorspar are recovered by Flotation of the cell-to-cell type, permitting maximum recovery and grade of concentrate. Wide acceptance of machines is well verified when considering that over 95% of all acid grade fluorspar is processed in the “Sub-A” Flotation Machine.Acid Grade Fluorspar Beneficiation Process Machinery And
