In this process a refractory lined Rotary Kiln of 42 Mtr long is used for reduction of iron ore in solid state. The kiln is mounted with a slope of % down words from the feed end to the discharge end. A central burner loed at the discharge end is used for initial heating of the kiln.

It is Coal Fuel based DRI. Coal based Spongeiron is a metallic product produced through direct reduction of iron ore in the solid state .As such it is also known as Direct Reduced Iron (DRI). Iron Ore Pellet is used for reduction.
Rotary kilns have a drawback upon the size and quality of iron ore that can be used. Initially, when the process was first introduced, the ore with an iron content >/= 65% was preferred and the preferred size of ore was 518mm. And coal of minimum "B" grade was required to be used for the solid state reduction or DRI making process
Coalbased reduction and magnetic separation behavior of lowgrade vanadiumtitanium magnetite pellets were studied in this paper. It is found that the metallization degree increased obviously with an increase in the temperature from 1100 °C to 1400 °C. ... has researched the solid state reduction of titanomagnetite concentrate in Panxi ...
Charge material, preheated to about 900 to 950 degree C enters the reduction zone. Temperature of the order of 1000 to 1050 deg C is maintained in the reduction zone, which is the appropriate temperature profile to facilitate solidstate reduction of iron oxide to metallic iron.
The solidstate metalized reduction of magnesiumrich lownickel oxide ore using coal as a reductant was studied based on thermodynamic analysis. The major constituent minerals of the ore were...
REDUCTION BEHAVIOR OF HEMATITE IRON ORE PELLETS 253 understanding of the kinetics of iron ore reduction by coal is essential. OMC Ltd. some of which have been applied to the solidstate reduction of iron ores. G.
The coal used in the Corex/Finex processes is required to supply heat for the devolatilization of the coal, the gasifiion of the char, and the melting of the reduced iron from the reduction shaft. It is also to provide sufficient gas to the reduction shaft to reduce the iron ore feed.
The reduced iron is in a solid state and will need an electric arc furnace to melt the iron. An experimental pilot plant is planned in Sweden, with market rollout foreseen for 2030. The experimental processes, known as ULCOWIN and ULCOSYS, are electrolysis processes to be tested on a laboratory scale.
Section 101. Short title. This act shall be known and may be cited as the "Solid Waste Management Act."
Iron production requires iron ore, coal and stone ... Direct Reduction . Several solidstate reduction processes have been developed in which iron ore is converted to metallic iron without melting. Because there is no separation of iron from gangue in the reduction facility, highgrade ores or concentrates (>90 per cent iron) must be used. ...
Directreduced iron (DRI), also called sponge iron,[1] is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture, the majority of which is hydrogen (H2) and carbon monoxide (CO) which act as reducing agents.
