Carbothermic reduction of Electric Arc Furnace Dust via thermogravimetry
Ferreira, Felipe Buboltz; Flores, Bruno Deves; Osorio, Eduardo; Vilela, Antonio Cezar Faria (2018) [Artigo de periódico]Electric Arc Furnace Dust (EAFD) is a solid waste originated from electric steelmaking furnaces. Currently, according to some authors, there is an estimated generation of 15 to 25 kg of dust per ton of steel produced. The ... -
Evaluation of zinc removal and compressive strength of self-reducing pellets composed of Electric Arc Furnace Dust
Ferreira, Felipe Buboltz; Flores, Bruno Deves; Osorio, Eduardo; Vilela, Antonio Cezar Faria (2019) [Artigo de periódico]The amount of Electric Arc Furnace Dust (EAFD) is continuously increasing in mini-mill steel plants. This dust is considered a hazardous waste because of the presence of elements like lead, cadmium and chromium. Among many ... -
