In this process, apatites (nearly always fluorapatite) are reduced in the presence of carbon and silica (gravel). This is performed in a submerged-arc furnace at temperatures of between 1150 and 1400C. The main internal reaction is described below: Ca 10 (PO 4) 6 F 2 + 15C + 9SiO 2 → 3P 2 (g) + 9[(CaO•SiO 2)] + CaF 2 + 15CO(g)
