Abstract
In this study, the integrated iron and steel plant mill scales prepared to concentrate in different ratios by blending with hematite character ore. CMC was used as binder and coke will be used as reductant. The calcite was added in such a way that the basicity ratio is 0.7. The pelletizing machine was pellet the blends containing the mill scales at different ratios and then drying at a temperature of 150 °C. 28 kg / pellet compressive strength was obtained in the pellets prepared from 100% mill scales. As the amount of ore increased, 45 kg / pellet was reached with a 50% increase in compressive strength. After compression tests, dried pellets were subjected to reduction at 3 different temperatures (1200, 1300 and 1400 C) and their reduction degrees were calculated based on oxygen loss. The highest reduction degree (82%) was obtained at 1400 ° C from the completely prepared with mill scales.
