33.  Studies Concerning the Possibilities of Manganese Recovery from Steel Slag by HCl and HNO3 Extraction

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


Abstract:

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


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