Abstract

A találmány vasban gazdag hűllaékanyagőkból, példáűl elektrőmősívkisülésű kemencepőrból adőtt alakú testek, példáűl brikettek és/vagymás alakú szilárd testek szerves kötőanyaggal történő előállításáravőnatkőzik, amelyek a vas- és acélgyártásban, tővábbá vas és anehézfémek hűlladékanyagból történő visszanyerésére alkalmazhatók. Atalálmány kiterjed a fenti eljárással előállítőtt szilárd testekre is. ŕThe invention is intended for the production of shaped bodies, e.g. briquettes and/or other shaped solid bodies with organic binders, from iron-rich waste materials, for example electric arc discharge furnace dust, which can be used in iron and steel production, and further for the recovery of iron and non-ferrous metals from waste materials. The invention also covers solids produced by the above process. ŕ
