    Estimating the lump to fines composition split in iron ore

    When ore is crushed and split into lump and fines components, there are systematic differences between the lump and fines compositions. The lump component is usually (but not always) richer in iron, and with less silica and alumina, than the fines product. The lump and fines composition targets are

    01-01-2015· For iron ore lumps, this change in source led to increases in the amounts of fines (owing to the greater fragility of BIFs compared to hematite ores) and the contents of Al 2 O 3 (owing to the contaminants found in clays), and SiO 2 present in iron ores (Santos and Brandao, 2003). These factors have exerted negative impacts on the steelmaking process.

    Developments in iron ore comminution and classification

    01-01-2015· Iron ore processing by Rio Tinto in the Pilbara region of Western Australia does not involve any chemical treatment. Flowsheets for the Brockman 2 and Paraburdoo processing plants are given in Figures 8.4 and 8.5 (Kinnel, 2013). The flowsheets are relatively simple. Dry processing involves up to three crushing circuits to produce lump and fines.

    The Disadvantages of Using Lump Ore. One disadvantage of using lump ore is increased fines generation. This will vary depending on the lump ore characteristics. Generating additional fines in the furnace would have the following effects: Increases the furnace delta (Δ) P. Can promote channeling. Increases yield losses by 1-2%.

    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)) or siderite (FeCO 3).
