Sintering Fundamentals of Magnetite Alone and Blended

SFCA formation in magnetite sintering occurs primarily in the cooling stage as magnetite oxidation is rather limited prior to the arrival of high temperature zone. Porous hematite and Marra Mamba ores are easy to react and hence assist melt formation.

UTILIZATION OF IRON ORE SLIME IN INDIA- AN REVIEW

2015-1-8  Indian hematite ores are typically rich in iron but contain unusually high alumina (as high as seven percent. The current practice of iron ore washing in India results in three products, namely coarse ore lumps directly charged to blast furnace, the classifier fines (3-5% alumina) which with or without beneficiation are fed to sintering plants and the slimes (6-10% alumina) which are currently discarded as waste, the slimes
