The effects of microwave and conventional oven drying on the drying kinetics and the quality of the ilmenite-coke composite pellets are presented. The drying time was substantially reduced in microwave drying (90 s) compared to conventional oven drying (10 min) for the exact size of composite pellets. The activation energy values in microwave …

The chemical composition of the ilmenite concentrate is shown in Table 1.As can be seen from Table 1, the concentrate is a low-grade resource of ferruginous ilmenite as it consists of around 50% TiO 2 and 34% FeO. XRD analysis of the sample reveals that the main phases in the sample are ilmenite (FeTiO 3) and hematite (Fe 2 O 3) (Fig. …
