Determination of ZnO Amount in Electric Arc Furnace Dust and Temperature Dependence of Leaching in Ammonium Carbonate by Using of X-Ray Diffraction [PDF]
Zinc is present in electric arc furnace dust (EAFD) mainly in two basic minerals, namely as franklinite ZnFe2O4 and/or zincite ZnO. While zincite is relatively reactive and easily treatable, franklinite is considerably refractory, which causes problems ...
