Process for processing stainless steel slags
A process for processing stainless steel slags, wherein these stainless steel slags are crushed to a particle size which is mainly smaller than about 60 mm at the most and wherein the crushed steel slags are processed further to produce a shape retaining mass containing the particles of the crushed steel slags in a bound state. Use can be made herefor of a hydraulically binding agent such as cement and/or fly ash, asphalt or synthetic material or of a fine fraction of the crushed steel slags themselves since they also have hydraulic properties. Due to the binding of the particles in the shape retaining mass, the problem of leaching, in particular of chromium, nickel and fluoride, is solved. In order to avoid swelling of possible free lime present in the crushed steel stags, these steel slags are brought into contact with water to reduce the free lime content to a value lower than 1% by weight at the most.
