| Abstract: | The effect of particle size distribution of specular hematite concentrates on sintering process and on various sinter properties were studied to assess whether the “as produced” or a comparatively coarse or fine concentrate is preferable. The results demonstrated that at basicity levels <2.0, a coarse ground concentrate would be preferable for improving both sinter quality and productivity. At higher basicities of ≥2.0, the effect of particle size distribution appears to be less pronounced, and the benefits obtained are marginal. The influence of particle size distribution and basicity on the formation of calcium ferrites has been discussed. |
