[PDF] Iron Ore Agglomeration Technologies

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of highgrade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration process

Environmental Assessment of Iron Ore Agglomeration

A study was carried out to compare the environmental impacts of the two major iron ore agglomeration processes, sintering and pelletising, using life cycle assessment (LCA) methodology. The following agglomeration processing routes, with the fuel options shown, were investigated: sintering with combined natural gas/coke breeze or charcoal as fuel, grate-kiln pelletising with combined natural

Utilization of Iron-Bearing Dusts in Iron Ore Sintering

As we know, the innovative process named composite agglomeration process (CAP) has a series of advantages compared to traditional sintering process (TSP). In CAP, part or all of the iron-bearing dusts is made into green pellets with 5–15mm in diameter, while the rest of iron-bearing dusts and all of the other fine ores is granulated after

2011-5-8  In a reduction roasting process the nonmagnetic iron is converted into magnetite (Fe 3 O 4), or maghemite (γ-Fe 2 O 3). Ore fines of 0–3 mm were treated with coal (10, 15, and 20%) at different temperature (500–750 °C) and passed through the low intensity magnetic separator (0.2–0.3 Tesla). The iron present in the form of hematite

Agitative Agglomeration

2018-1-4  Iron ore processing is the largest tonnage of material being pelletized by agitative agglomeration in which there is no chemical reaction between the particles and the liquid. Since it is a large tonnage product and since it is easy to study, much investigation has been done regarding this type of the ball formation.

Utilization of Iron-Bearing Dusts in Iron Ore Sintering

Iron-bearing dusts, containing valuable constituents such as Fe, CaO, MgO, C, etc., are generally utilized as raw material in iron ore sintering. However, the dusts characterized by low granulating and refractory performances always lead to negative effects on sintering indexes.
