  • Slag recycling recovery

    Of the 163 Mta of steelworks slag in Europe, 523 % are BOF slag, 349 % are EAF slag and 126 % are other types of steelworks slag Of this amount, 118 Mta or 724 % was recovered, 153 % went to interim storage and 123 % to dumps and landfills The recovery or recycling quantities are shown in Fig 8The newest technology ECOFERTEC slag processing plant enables the most costeffective way to remove steel from slag with 300 ton/h capacity One plant can handle 1,5 M ton of slag per year in two shifts Ecofertec designed processes has always the highest processing rate and the lowest electricity consumption possible for each solutionSteel Slag Processing — EcofertecConventionally, little chemical adjustments are made to the slag prior to its processing for subsequent use or disposal However, recent attempts have looked intoGranulation and Heat Recovery from Metallurgical Slags
