Principles of Extractive Metallurgy

2013-1-18 · • Carbothermic reduction of iron ore (Hametite) in blast furnace is a well known process. Overall process is written as: • Ironore oxide mineral + gangue + Reducer (C) + flux + hot blast oxygen enriched air = Pig iron (liquid) + Slag (liquid) + waste gas (CO,CO2,N2) • Iron ore contains Fe2O3, along with gangue materials such as SiO2, Al2O3.

Novel Binders and Methods for Agglomeration of Ore

metallic iron from ore directly, in a single step. A particularly promising approach is the iron nugget process, where pellets are made that consist of iron oxide concentrate, powdered coal, flux, and a binder. When these pellets are heated, they self-reduce to form metallic iron droplets that separate from the slag.
