Abstract

Binders are of prime importance in the agglomeration of iron ore concentrates. In this research, strength and density of briquette produced from the magnetite concentrate of Gol-E-Gohar were investigated using different binders at various applied pressures. The results showed that peridor was the most effective binder relative to bentonite and lime. For all types of binders, the increase in binder content increased the strength and decreased the density of briquette. The increase in the applied pressure during the preparation of briquette also increased strength and density, but this occurred at different rates when different types of binders were used.
