The increasing cost of recovering magnetite from iron ore an‎d the decline in titaniumore have led to a growing interest in alternative sources within the metallurgical industry, such as titanimagnetite ores. The technologies utilized for processing titanomagnetite ores include blast furnace an‎d direct reduction methods, each of which has its own advantages an‎d disadvantages. The use of high-grade methods should result in minimal environmental pollution. One environmentally safe method is the reduction roasting technique using a fixed bed reactor. In this study, the reductive roasting process was investigated using methane gas as the reductant, with initial temperatures of 550◦C an‎d 650◦C, secondary temperatures of 800◦C,900◦C an‎d 1000◦C, an‎d gas flow rates of 1 liter/min an‎d 2 liter/min. Low-intensity magnetic separation was performed on particle sizes below 400 mesh in a fixed bed reactor. Ln reductive roasting at different temperatures, we achieved an iron grade of 54.79% an‎d a titanium dioxide grade of 7.91% at the optimum temperature. Ln reductive roasting with varying flow rates, we attaind an iron grade of 59.45% an‎d a titanium dioxide grade of 7.02% at the optimum flow rate. Additionally, in low-intensity magnetic separation, we reached an iron grade of 61.38% an‎d a titaniumdioxid grade og 7.17%.
