Iron ore pellets - an overview | ScienceDirect Topics

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The ...

Mineral Reactions and Slag Formation During …

pellets are made by adding binder to finely ground iron ore and pelletised in a balling drum or disc pelletiser. These so called green pellets are fired in an induration process up to 1350°C. Several additives may be added to gain certain slag forming properties in the blast furnace. Important characteristics of pellets in the blast furnace are their reducibility, low temperature ...
