Abstract:
In this work, pyrometallurgical techniques were used to recover a portion of iron present in iron oxide form in slag of LD steelmaking process. Various reducing additions were tested in molten slag in pot, resulting in a significant recovery of iron with low phosphorus and sulfur content that enables reuse of this material as scrap in production and refining pig iron.
