Measurements have been made to study the effect of the addition of an alkaline or alkaline earth metal sulfide such as Li2S, K2S, MgS, CaS, SrS or BaS to FeS flux on the copper distribution ratio between FeS flux and carbon saturated liquid iron at 1 673 K. Since solubility of MgS and CaS is limited, no apparent effect on copper distribution ratio was observed. Addition of Li2S, K2S, SrS or BaS to FeS increased the copper distribution ratio, LCu = (mass%Cu)flux/[mass%Cu]Fe, and reached maximum value at a certain content of these additives. The maximum values of LCu measured in each flux were 30, 20, 22 and 19 in FeS-LiS0.5, -KS0.5, -SrS and -BaS fluxes, respectively. The sulfur content also decreased by the addition of these sulfides.
