Contribution to the investigation of nickel transfer between nickel‐bearing electro‐reduction‐furnace slags and iron‐nickel bath

The transfer of nickel between electro reduction furnace slags as produced from the reduction treatment of Greek laterites in Larymna and ferronickel (Fe–Ni), was studied. These SiO 2 –FeO‐CaO–MgO–Al 2 O 3 – x ( x = S, P 2 O 5 , Cr 2 O 3 , NiO) slags were used for the laboratory experiments, which were performed in a 25 kW, 10 000 Hz induction furnace. The theoretical aspects of the nickel transfer from the ERF‐slags are presented. The overall mass transfer coefficient k g was experimentally determined. The temperature dependence of k g [cm/s] is given by the relation: In .
