IN258295: An improved process for the preparation of titania rich slag and metallic iron from metallized ileminite in an improved inflight thermal plasma reactor

The invention provides a process for the preparation of titania rich slag and metallized iron from the metallized ilmenite using an extended arc plasma reactor. Thermal plasma technology is emerging as one of the eco-friendly route for processing of ilmenite. Production of TiO2 rich slag from metallized ilmenite by thermal plasma is gaining importance due to increased demand for slag as feed material in the pigment industry. A modified thermal plasma process has been developed using in-flight techniques wherein a closed graphite bed reactor has been used for making TiO2 rich slag from metallized ilmenite. Using this process power consumption is reduced considerably.
