EAF DUST TREATMENT BY PELLETISING AND FLUIDISED-BED REDUCTION
摘要
<p>The invention concerns a process for the treatment of EAF (electric arc furnace) dust. In the process preheated and decontaminated EAF dust is introduced into a fluidised bed reactor in which hematite is reduced by means of a hot reducing gas generated by reforming natural gas in a non-catalytic plasma-arc heating process. This produces an iron-rich material suitable for recycling to the electric arc furnace. The invention is characterised in that the EAF dust is pelletised prior to introduction into the fluidised bed reactor.</p>
