EAF Dust

Product name:EAF Dust

Product description:Steel production by electric-arc furnace (EAF) technology has been increasing in importance over the past 20 years at the expense of traditional open hearth and basic oxygen converter technology, reaching an estimated 33.4% world share in 1999. This trend looks set to continue, and it is expected, for example, that more than 50% of the steel produced in the USA will be by this route within the next few years (1999: 46.2%). When steel is produced using an electric arc furnace, about 15 - 20 kg of dust is formed per tonne of steel. This dust is considered as a toxic waste due to its content of heavy metals. It is estimated that the world-wide total production of EAF dust could be as high as several million tonnes, all of which must be treated, recycled or land-filled.
