The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the blast air to form molten reduced iron, carbon monoxide (CO), and slag. The molten iron and slag collect in the hearth at the base of the

This review focuses on the usability of iron ore ultra-fines for hydrogen-based direct reduction. Such technology is driven by the need to lower CO2 emissions and energy consumption for the iron and steel industry. In addition, low operational and capital expenditures and a high oxide yield because of the direct use of ultra-fines can be highlighted.

The iron ore in this area contains a large volume of fines (20–30% below 150 μm), which can be transformed by high moisture content into a sticky mass that is almost impossible to screen. Vale initially considered wet-process screening using water sprays to overcome the problem but ultimately rejected that approach as too costly.

Use of Direct Reduced Iron (DRI) in the Electric Arc Furnace (EAF) for Steelmaking; Shipping and handling of DRI. Being a highly reduced material, DRI has a tendency to re-oxidise, an exothermic reaction. Thus, without appropriate precautions being taken in its handling, transport and storage, there is a risk of self-heating and fires.

The magnetic drum catches cast-iron fines while at the same time indexing against a stainless steel blade that scrapes the fines off the drum. Once enough material has collected to form a heavy sludge, the sludge then drops onto the dry chip conveyor incline to be dragged along with the larger chips and fines and into the chip hopper.
