Reduction of Iron Ore Pellets, Sinter, and Lump Ore under …
Lump ore is the slowest to reduce in all studied temperatures. This may be because the particle size is largest, and hence it has the lowest reaction surface area. Even when the mass of all experimented iron-bearing materials is around 100 g, the number of samples for the lump ore is only 2, whereas for pellets it is 30 and for sinter 19. ...
