Abstract (en)
A process is disclosed for producing self-fluxing, sintered ores using a raw materials mix comprising at least 25 wt% of fine grains below 1 mm in size and not more than 5.4 wt% of SiO2 in terms of sintered ore product. The process is characterized by control of the SiO2 content of said fine grains to be at least 50 wt% of the total SiO2 content of the mix, and sintering of the thus controlled mix.
