Siderite ore – Siderite ore (Fig 3) is an iron carbonate with a chemical formula of FeCO3 (iron carbonate), a theoretical iron content of 48.2 %, a FeO content of 62.1 %, and a CO2 content of 37.9 %. Common in nature is hard and dense siderite, the appearance of the colour is gray and yellow-brown, the specific gravity is 3.8, the hardness is between 3.75 …
The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).

Fig 1 Schematics of sinter mix and product sinter Sintering process is a generic term that is used to describe the process of agglomeration of a green mix of iron ores, fluxes and coke and plant solid wastes having a particle size of -10 mm so as to produce sinter which can withstand operating pressure and temperature conditions existing in a BF.
A smaller, but still considerable, amount of water is used as process water for beneficiation of iron ore, cleaning of raw gases (coke oven gas, blast furnace gas, and BOF gas), quenching of coke and slag, and descaling of steel etc. Process water is also used as part of chemical treatments, such as solvent in acidic pickling, matrix for ...
In this iron ore deposits (mentioned above), the iron ore was crushed using three stages of crushing to a size below 32 mm and then was subjected to beneficiation. Primary and secondary crushing was done by gyratory crushers. For sticky iron ores with a high clay content, primary and secondary sizers were also used instead of gyratory crushers.
The process of enriching taconite ore involved grinding the ore to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high grade ore is in the form of fine particles, as small as 0.1 mm or less, which are not suitable for sintering.
Typical burden of 1.0 million tons per year Midrex unit at Comsigua, Venezuela consists of 80 % iron ore pellet and 20 % iron ore lump. Typical analysis of feed materials for this plant is given in Tab 2 and typical analysis of the pr0duct is given at Tab 3.

Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice. This also applies to iron ores of the non-magnetic type which after a reducing roast …
Mining (extraction), beneficiation, and processing of iron ore produces iron and steel. Mining is defined as removing ore material from a deposit and encompasses all activities prior to beneficiation. High grade iron ores (iron content greater than 62 %) are simply crushed, screened and shipped directly to the iron making unit (e.g. blast furnace).
Beneficiation of Iron Ore. The purpose of beneficiation is to provide the following advantages: less amount of added elements in the ore; Increase the reduce ability of the ore; make the ore suitable for transport; The only processing steps used for ores mined from rich deposits (rich ores) are …
Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % to 63 % Fe) hematite iron ore. The wet process consists of multi-stage crushing followed by different stages of washing in the form of scrubbing and / or screening, classification etc., but the advantage is only partial removal of adhered alumina and free silica …

Energiron direct reduction process (HYL process) uses a shaft reduction furnace to produce DRI. It is designed to convert iron pellet/lump ore into metallic iron by the use of reducing gases in a solid-gas moving bed shaft furnace. O2 is removed from the iron ore by chemical reactions based on H2 and CO, for the production of highly metallized DRI.
Raw materials consisting of iron ore fines, coke breeze, slag modifiers such as lime stone, dolomite, manganese ore, lime, quartzite, and sand etc., and waste materials such as mill scale, screenings, dusts, sludges, and converter slags etc. are batched and conveyed to a blending system.
The first one is iron bearing materials which are sinter, pellets and calibrated iron ore (CLO). Higher iron (Fe) content in these materials means lower gangue material is going inside the furnace which needs to be fluxed for slag formation. Hence higher Fe content helps in the reduction of slag volume and coke rate.
This plant has a capacity of 200,000 tons per year and is based on the processing of iron ore without its beneficiation from Pang Pet ore deposit. Pang Pet ore deposits have Fe content of up to 29 %. ... The process utilizes …
Hydrogen based Fine-Ore Reduction (or HYFOR for short) is the world's first direct-reduction process for iron-ore concentrates from ore beneficiation which does not need any pre-processing of the material like sintering or pelletizing. This reduces CAPEX and OPEX costs. ... About IspatGuru.
The US iron making has historically been based to a large extent on pellets primarily because all the local iron ores needed beneficiation (up grading) by grinding it to fine particles (< 0.1 mm) and agglomerating these fines into pellets but also because sinter plants are not used due to environmental reasons.
