Abstract
The metal oxides contained in electric arc furnace(EAF) dust are reduced by solid carbon at the various temperatures and basicities to investigate their effects on the reduction reaction and rate. A thermogravimetric analysis(TGA) was also carried out for franklinite to show that the zinc oxides could effectively be reduced and evaporated completely at the temperatures above 1100℃. The X-Ray diffraction study of reduced EAF dust revealed that the slag was a mixtures of Merwinite[Ca₃Mg(SiO₄)₂]. apparentely crystallized first and Akermanite [Ca₂MgSiO_7] as the second crystallization product. The reaction rate constants evaluated for zinc removal reaction and also the reduction reaction of metal oxides are found to be expressed as a classical Arrhenius type relation with the temperature.
