23.  Studies Concerning the Possibilities of Iron Recovery from Steel Slag, by Acid Extraction in HCl and HNO3

Authors: Adina Berbecea, A. Iovi, P. Negrea


Abstract:

In this paper, we studied the possibilities of iron recovery from steel slag which is a result of steel manufacturing in Siemens-Martin furnace, on Metallurgical Plant Resita. Steel slag was put into extraction in HCl and HNO3 with various concentrations and different values of liquid : solid ratio and extraction time. During lab experiences we derived some conclusions and settled the optimal conditions for iron recovery.


Keywords: steel slag, iron recovery, acid extraction, optimal conditions
