Abstract (en)
[origin: WO9631630A1] Waste material containing heavy metals are mixed with oily mill scale or with reduced iron or fines and with a fine grained carrier material having a low density until a crumbly mixed product results, of which a fine fraction of between 0 and 6 mm in grain size is sievable for injection into a metallurgical furnace. Water may be added to the mixed product using wet carbon-containing slurries. Lime-containing dusts may be added.
