Iron ore (fines)

2  · Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH).n(H 2 O)) …Coarse and Fine Particle Flotation Recovery2016-6-2 · Coarse and Fine Particle Flotation Recovery. In The Days of gravity concentration, the art of ore dressing developed on the cardinal principle of saving the values at as coarse a size as possible. Flowsheets were designed which featured an alternation of crushing and concentrating operations. Thus an ore might be crushed to ½ inch, jigged to ...

These iron ore fines cannot be directly used in the blast furnace as they pose the following threats: 1. Iron ore fines severely reduced the permeability of the bed, jeopardizing the reduction reaction in the blast furnace 2.Effects of Aggregate Size, Shape, and Surface Texture on ...percentage of material in the 30, 50, and 100 mesh sizes. Permeability is a matter of pore size rather than void volume. Workability is most affected by the quantity and grading of coarse aggregate. Finally, critical mixtures (those very sensitive to bitu-men content) are associated with high percentages of fines.
