10–20% of the iron was separated as metal, and the rest remained in the slag as iron particles. Although about 30% of the P 2O 5 was reduced, approximately 20% of the reduced phosphorus was absorbed in the metal. In Experiment 21, in which the slag with a lower Fe tO content and basicity was reduced at 1 473 K, only 20% of the Fe
