Abstract Scope Recyclability of electrical-arc furnace dust (EAFD) in the form of a briquette was analyzed. Kinect behavior of the briquette’s self-reduction and in contact with molten steel (steel-briquette system) was investigated. The optimal briquette composition used to recover elements such as Cr, V and W was targeted. The dust as-received was magnetically separated to the form of a magnetic (M)EAFD then characterized analytically and microstructurally. Three different compositions of briquettes were prepared: first with 84% of MEAFD and 16% C; second with 82% of MEAFD and 18% C; and third with 80% of MEAFD and 20% C. Reduction experiments at the temperature of 1500°C were carried out to study the rate differences. Reduction experiments showed that the fastest reaction occurred in the briquettes with 20% of C for both systems. The optimal measured recovery was 48.1% Cr, 72.7% W and 47.5% V (in wt.%).
