Abstract

The invention relates to a method for the treatment of steelwork slag for producing a hydraulic mineral binder with high curing potential and for recycling iron. To this end and according to the invention a source product containing steelwork slag and MnO is prepared. This source product is further processed as a melt by introducing reducing agents into the melt. The mineral content of the melt should reach a lime standard of between 90 and 110. The melt is then cooled under defined conditions and elemental iron is mechanically separated from the solidified melt. The solidified melt is then fed to be used as a hydraulic mineral binder. The invention further relates to a hydraulic mineral binder.
