Iron Ore Agglomeration Technologies

Because of these processes, a fine granulometry is produced, and thus iron agglomeration process is necessary. There are several agglomeration processes including: briquetting, extrusion, nodulization, pelletizing and sintering, although pelletizing and sintering are the most widely used, and especially sintering process (70% blast …

Conventional Sintering Effects on the Microstructure and …

Conventional, free or pressure less sintering is the simplest technique which involves heating of a powder compact, previously prepared at ambient temperatures, without applying any external pressure. It can be conducted with various box furnaces or tube furnaces under different atmospheres (oxidizing, reducing, inert, and vacuum). …

Traditionally, fine ores are treated either by the process of sintering and/or by pelletizing to prepare an agglomerate with suitable metallurgical characteristics for ironmaking processes.

Rietveld study on the effect of pelletizing and sintering …

This research aims to investigate the effect of pelletizing and sintering on the crystallinity of LATP. LATP powder was synthesized via a sol-gel method and mechanically pressed into pellets and sintered. Morphology and structural features of the LATP samples (powder and pelletized samples) were characterized using a scanning …

Effect of polydisperse sintering ore on the pelletizing of fine

An addition of the polydisperse Yakovlevo deposit sintering ore on the efficiency of pelletizing and, hence, the gas permeability of a sintering mixture containing fine concentrates is studied. This sintering ore is found to have unique properties, which make it possible to increase the iron content in a sinter and to improve the gas …

SINTERING AND PELLETISATION OF INDIAN IRON ORES

Emission Optimized Sintering (EOS®) for lower costs Iron ore sintering creates substantial off-gas volumes, and treating these in order to meet increasingly stringent environmental standards is expensive. EOS® uses recycling technology to reduce off-gas volumes by 40 to 50 %, resulting in smaller secondary gas treatment systems. This means:
