A binder adapted for pelletization of sinter raw mix based on ilmenite process industry waste

摘要

A binder for sinter raw mix for making pellets such as in iron ore sintering and, more particularly, to Ilmenite (FeTiO3) process industry waste as a binder replacing burnt lime in iron ore sinter raw mix in iron ore pellet plants and a process for sinter production using said binder. Importantly, said process ensure achieving improved permeability of sinter bed and higher productivity utilising Ilmenite process industry waste as binder which contain various forms of iron oxides viz. iron hydroxides, hydrated iron oxides and iron oxide, depending upon moisture content and temperature, to recover its iron value and as a binder in iron ore sintering and iron ore pellet making plants. The process according to the invention thus favour achieving on one hand improved permeability of sinter bed, sinter quality and strength and on the other hand providing iron value through the iron oxide based waste as binder ensuring enhanced sinter production rate and reduced sinter fines generation.
