Porosity and Reducibility of Extrusion Briquettes - academia.edu

Both extrusion briquettes and iron ore are fired from 1000°C to 1500°C for 2 hours in step of 100°C. Reducibility was determined from oxygen loss calculated from weight. Metallic iron content and metallization was evaluated. Reducibility, metallic iron content and metallization of iron ore and extrusion briquettes are given in Table 5.

Abstract: Ores of infiltration sandstone-hosted uranium deposits in the sedimentary cover are ubiquitous composed of dispersed soot powder mineralization of black, brownish-black colour. Long-term studies of such loose U-ores by analytical transmission electron microscopy (ATEM) proved their polymineral nature. Uranium blacks are composed by at least three different U-mineral forms: oxide ...
