CHAPTER11 FUNDAMENTALS OF IRON ORE SINTERINGiron oxides are the major mineral phases for siliceous sinter, the ferrites, magnetite and mixed calcium iron silicates are the major mineral phases for fluxed sinter . Sintering is a fast process and it is unlikely that equilibrium will be reached during sintering. The reaction mechanism proposed for self fluxing sinter is summarized below :
SINTERING MECHANISM OF MAGNETITE PELLETS DURING .Sintering is one of the critical phenomena during the induration process, especially, for magnetite pellets where it often occurs for both the phases oxidized magnetite (hematite) and non– oxidized magnetite (magnetite) [1]. Sintering is a complex process involving transport of species
