This study was performed by chemical analysis and metallographic observation. Chemical properties were analized by ICP, XRD and SEM-EDS and slag structures were observed by microscope and SEM. Total Fe amounts in A, C area of slag can be observed $39\~45\%$ by chemical analysis results. It was average of acient times. CaO was $3\~8\%$. It's not plentiful but we think that was artificial. Ti was found in A area a little, and Ti, V were found in C area so much. The compounds, as if Fayalite, Wustite, Magnetite, Ilmenite, Pseudo-brookite, Ulvospinel, Forsterite, Fephroite, Olivine were observed in the result XRD. These structures were also observed in microscope and SEM image. Therefore, The furnance of A area usually used an iron mine, An Iron furnance of C area considered it which refined using a raw iron mine and a raw iron sand.
