主 题:SnS slag evaporation rate fuming
摘 要:Under inert atmospheres and 1473 K,the evaporation rate of SnS from SnO-FeO- SiO_2 and SnO-FeO-CaO-SiO_2 slags mixed with FeS was investigated by measuring the weight Ioss and composition of *** experimental results show that dur- ing sulfide fuming process the evaporation of SnOfrom slags is negligible in comparison with that of *** of CaOto slags can enhance the evaporation rate of *** differential rate equation of evaporation may be expressed as: -d(%Sn)/dt=k(%Sn)(%S) where,the apparent rate constant k was found to be 4.20×10^(-3) for SnO-FeO-CaO- SiO_2 system and 2.88×10^(-3) for SnO-FeO-SiO_2 system,respectively.
