Iron and Steel Emissions | Global Greenhouse Warming
Iron is the most abundant element by mass of our entire planet, making up 35% of the mass of the Earth as a whole. Steel is an alloy consisting mostly of iron, with a carbon content between 0.02% and 1.7 or 2.04% by weight (C:1000–10,8.67Fe), depending on grade.

What is direct reduced iron (DRI)? definition and …
direct reduced iron (DRI): Alternative iron source produced by heating an iron ore (generally having 65 to 70 percent iron) at a temperature high enough to burn off its carbon and oxygen content (a process called reduction) but below iron''s melting point(1535°C or 2795°F). The output is sold as pellets or briquettes (called hot briquetted iron

In the Finex process, fine iron ore is charged at the top of a cascade of fluidized-bed reactors where it is heated and reduced to direct-reduced iron (DRI) by means of a reduction gas – derived from the gasifiion of the coal – that flows in the counter-current
WELSPUN STEEL LIMITED
Sponge iron is a metallic product produced through direct reduction of iron ore in the solid state. It is a substitute for scrap and is mainly used in making steel through the secondary route. The process of sponge iron making aims to remove the oxygen from iron ore.
The Lion Group
Its newest addition, a Direct Reduced Iron (DRI) plant in Banting, using Midrex technology has a capacity of 1.70 million tonnes per annum. The increased supply of DRI will help to reduce the dependence on scrap as raw material for steel making by the Group’s various steel mills and enable the production of high quality steel.

HIsarna ironmaking process - Wikipedia
The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron or hot metal. The process coines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.
