EAF Dust

Over the years, there has been growing concern over the waste by-products left behind by steel production. One of these by-products is a fine dust created by electric arc furnaces (EAFs) and this causes a whole slew of problems ranging from mechanical failures to health and environmental issues. Before, production facilities would have to invest a great amount of time and money to treat and dispose of the dust in a safe and responsible manner. But recent advances in technologies now provide more efficient and sustainable methods for handling and recycling EAF dust. The dust contains high amounts of zinc that can be separated through the Waelz Kiln process. This can then be re-sold to zinc smelters as an alternative to concentrates from mines. Through the process, iron pellets are left behind which can also be used as cement and road fill.
