Slag recycling recovery

Of the 16.3 Mta of steelworks slag in Europe, 52.3 % are BOF slag, 34.9 % are EAF slag and 12.6 % are other types of steelworks slag. Of this amount, 11.8 Mta or 72.4 % was recovered, 15.3 % went to interim storage and 12.3 % to dumps and landfills. The recovery or recycling quantities are shown in Fig. 8.

Laboratory Treatments of EAF Slag for its Use in

Laboratory treatments of a plant EAF slag sample 71686 were conducted using stabilizers containing P2O5 and air granulation. The results show that it is necessary to add the stabilizers to increase contents of P2O5 from 0.39% to 0.7% for the slag stabilization. By a fast air cooling, most of the granules from the granulation are spherical, with a low internal porosity and dense structure.
