Abstract

In this present study, the reducing products of carbonthermal reduction of ilmenite ores were evaluated. The crystal structures, microstructure and surface chemical functional groups of the ilmenite ores and the reducing product of carbonthermal reduction were also analyzed using XRD, SEM, Raman and FT-IR, respectively. Sulphate titanium slag and high titanium slag were the major reducing products of carbonthermal reduction of ilmenite ores. It was found that the low-valent titanium of high titanium slag was increased after carbonthermal reduction of ilmenite ores with higher temperature and longer processing time. Based on the results, this method could be applied effectively and efficiently way for both utilization of ilmenite ores and preparation of sulphate titanium slag and high titanium slag.
