• Measurements have been made to study the effect of the addition of alkaline or alkaline earth metal sulfide such as Li2S, K2S, MgS, CaS, SrS or BaS to FeS on the copper distribution ratio between FeS flux and carbon saturated liquid iron at 1 673 K. Since each solubility of MgS and CaS in liquid FeS was limited, no apparent effect of MgS or CaS on the copper distribution ratio was observed. Similar to the effect of Na2S studied in our previous work, the addition of Li2S, K2S, SrS or BaS to FeS increased the copper distribution ratio, LCu=(mass%Cu) flux/[mass%Cu] Fe, and LCureached maximum value at certain content of these additives in each flux. 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 in liquid iron also decreased by the addition of these sulfides to FeS.
