EAF DUST TREATMENT FOR HIGH METAL RECOVERY BY

2013-11-11  Electric arc furnaces (EAF) generate much dust during operation, which contains very high percentages of zinc, lead, and iron, as well as toxic organic substances. It is difficult to landfill it for environmental reasons, and not desirable in terms of wasting metal. However, most of the EAF dust is not processed sufficiently to make it harmless and to recover valuable metals.
