The non carbothermic zinc pyrometallurgical processing of electric arc furnace EAF dust was investigated on a laboratory scale The main objective of this process was to convert highly stable zinc ferrite ZnFe2O4 which accounts for more than half of total zinc in the EAF dust into ZnO and Ca2Fe2O5 by CaO addition The EAF dust was mixed with CaO powder in various ratios pressed

recycling the EAF dust for the production of pre cast agglomerate PCA for use in steel plant process extract the EAF dust hazardous constituents to allow reclassification to non hazardous waste not inert class II A according to ABNT NBR 10 004 2004
Recycling of electric arc furnace EAF dust for use in steel
Steel Manufacturing Electric Arc Furnaces Rationale for Standard Electric arc furnace EAF steel manufacturing is an important recycling activity which contributes to the recovery of steel resources and waste minimization However the nature of the process is
