The phosphoric iron employed to effect the jecomposition should be very high in phos- »horus, and should be first decarburized and jesiliconized in a silicous lined Bessemer -essel before running it into the vessel which contains the carbonate. The highly phosphoric iron made by smelting calcareous phosphoric slag with silicous phosphoric iron ore, or puddling cinder, is the material best adapted for the process. The phosphorus ontent of iron made in this way may be made to range between 6 and 30 per cent., snd an iron phosphite or ferrophosphorus ontaining very little carbon or silicon may be produced. The carbon in this phosphorus iron will, as a rule, be lo…
