2016-2-1 Recent studies on natural ilmenite ore (an iron–titanium oxide ore) , , , , showed good reactivity of this material as an oxygen carrier for CLC processes. In addition, ilmenite ore was found to fluidize well and did not tend to agglomerate at the temperature range of interest for this process, i.e., 800–950 °C. Finally, ilmenite ore has the advantages of low toxicity and low cost.
