Effect of Raw Material Composition on the Sintering Properties

2 and MgO, the sintering properties varied with iron ore type greatly. The sinters made from the dense low alumina iron ores presented the higher tumbler strength and the lower coke rate, but the RDI was not simply related to the alumina level of iron ore. A high alumina ore may produce the sin-ter with a very low or very high RDI.

Influence of Alumina on Iron Ore Sinter Properties and

Apr 23, 2010· Due to depletion of high grade iron ore resources, alumina content in the iron ore fines is expected to increase gradually. Ore with higher alumina content is usually expected to be detrimental in forming the sinter matrix, if sintered alone, due to the low reactivity of alumina bearing minerals and the high viscosity of primary melts.

Effect of Iron Ore Concentrate on Sintering Properties

iron ore concentrate contains a lower alumina. Recently it is more popular to be applied in commercial sinter plants to decrease the alumina content in sinter or combined with a high alumina low grade ore to reduce the production cost of sintering. However the productivity of sinter decreased with a decrease in the size of iron ore.
