Mechanisms In Oxidation And Sintering Of Magnetite Iron

Abstract. Thermal volume changes and oxidation mechanisms in magnetite iron ore green pellets balled with 0.5% bentonite binder, as a function of raw material fineness and pellet porosity, are shown. When a pellet starts to oxidize, a shell of hematite is formed around the pellet while the core still is magnetite.

Optimization Of Firing Temperature For Hematite Pellets

Conversion of magnetite to hematite is a strongly exothermic reaction and favours the grain growth and sintering of the particles of iron ore concentrate to form hard, strong pellets. 3) As the coke breeze increases this effect becomes more and more severe. During firing the carbon monoxide is generated in pellet due to incomplete combustion of ...

D.R.I. Fines. Direct-reduced iron (DRI), also called sponge iron is produced from the direct reduction of iron ore (in the form of lumps, pellets or fines) to iron by a reducing gas produced from natural gas or coal. Few ores are suitable for direct reduction. Reduced iron derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at high temperatures in ...
