Iron processing - Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and …
Quantitative XRD analysis of iron ore sinter and pellets3.5.1. Fundamental studies of sinter phases. Apart from natural iron ore, the Rietveld method has also been applied to study the phases presented in sintered iron ore, or iron ore sinter. A typical outcome from the Rietveld analysis of an iron ore sinter is shown in Fig. 3.4.
The present work proposes a novel process to sinter porous iron ore (porosity ~23–24%) with enhanced productivity and quality. The iron ore is pre-processed in the presence of calcined lime for the temporary closure of pores, which further prevents water absorption during the granulation process in drum in the presence of water. The …
