The FINEX Process :: Total Materia Article

A schematic of the process is shown below: Figure 1: The FINEX process. Molten Iron is produced directly using iron ore fines and non-coking coal rather than processing through a sinter plant and coke ovens as traditional blast furnace route. In the Finex process, iron ore fines are charged into a series of fluidized-bed reactors.

Iron Ore Pellet - an overview | ScienceDirect Topics

D. Zhu, in Iron Ore, 2015. 16.3.1.1 Background. In a DR process, iron ore pellets and/or lump iron ores are reduced by a reducing gas to produce DRI or hot briquetted iron (HBI). Depending on the generation of the reducing gas, two different DR processes are commercially available: gas-based and coal/oil-based.

Iron processing - Ores | Britannica

Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used.

Corex Process for Production of Iron - IspatGuru

The first stage of the process takes place in the reduction shaft, where iron ore burden is reduced by gases emanating from the melter-gasifier and is converted to hot DRI. Hot DRI is mechanically transferred to the melter-gasifier where the second and third stage of the process takes place.

The Process - Plant - Texas LLC

Direct Reduction – The cleanest and safest way of iron making. Most naturally occurring iron oxide has the composition of hematite (Fe2O3) and contains about 30% oxygen. The direct reduction process removes this bonded oxygen in the iron ore pellets at elevated temperatures by a reducing gas, which is produced from natural gas.

Introduction to Iron ore Pellets and Pelletizing processes

Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
