WebAug 14, 2012 · UK based ZincOx started hot commissioning its rotary hearth furnace (RHF) in Korea during Q1 2012 to process electric arc furnace dust (EAFD) to recover both a zinc oxide concentrate and briquetted direct reduced iron (HBI). The project, being built in two phases, is designed ultimately to treat 400kt/y of EAF dust containing an average Zn ... Webdiffraction (XRD) and TGA analysis. Laboratory and industrial trials on steel alloying with Mo were conducted using precursor mixtures as sources of Mo. It was found that the mixture, which contains FeO x, MoO 3 and C (Fe 2MoO 4 precursor), can provide the Mo yield up to 98 % at both the laboratory as well as industrial trials.
