Worldwide,iron ore sintering is the largest industrial single source of dioxin emissions~(1-3).Conversely, some ores may help in reducing emissions,because of their aptitude of(a) adsorbing and(b) oxidising or decomposing TOC and dioxins~(4,5).Such dioxin abatement abilities were tested for five types of ores,representing major ore origins(Australia,Brazil,and South Africa ),minerals(magnetite,haematite,goethite,pisolite ),and properties,e.g.porosity,and Loss on Ignition(LOI) values.In total,11 exploratory experimental runs were conducted on iron ores,to test the oxidation in air of four different organic trace test substances:acetone, chloroform,n-hexane,and toluene contained in a test gas were led simultaneously over the ore over a preestablished temperature program.Each test comprehends a first part with a programmed temperature rise,a brief soaking period at the temperature maximum(>400℃),and a ballistic cooling part.The concentration of the four organics is continuously monitored by Mass Spectrometry(MS) operating in a full-scan mode(m/e < 100). Exploratory experiments allowed differentiating the ores tested according to the Destruction & Removal Efficiency(DRE) attained.To check the results the products of oxidation in the effluent were sampled on Tenax and identified.Also,the dioxin load remaining on several test residues was examined and found to be quite limited (pg I-TEQ/g).
