It shows that the tem perature is more si nif icant than the carbon addition and sla basicit y on the recovery ratio of Fe and Ni. The recov ery ratio of Fe and Ni is hi her, which are close t o t he theoret ical values calculated w ith Fact sa e, w hen the tempera ture is 1550 , basicity is 1. 1 and the carbon dosa e is 6. 0% . On the other hand, basicity is more si nif icant than the temperature and the carbon addition on the Fe and Ni cont ent in the metal. The Fe and Ni content in the metal are hi her when basicit y is 1. 1 and the tem perat ure is 1550 .
