“…The alumina to silica ratio that is typically greater than one possesses serious operational problems during sintering and subsequent smelting in the blast furnace [16,17]. More specifically, high alumina content in iron ore and sinter leads to a viscous slag during smelting in a blast furnace.…”

“…More specifically, high alumina content in iron ore and sinter leads to a viscous slag during smelting in a blast furnace. This in turn requires a high coke rate [17] and results in some troubles during tapping of the viscous slag. Generalised contents for SiO 2 and Al 2 O 3 requirements in commercial iron ores are given in Table 2.…”

The study aimed at investigating the chemical composition and microstructure of raw iron ore from the deposits in Muko area (south-western Uganda). The quality of this iron ore was evaluated to establish its suitability to serve as a raw material for iron production. Samples were taken from the six hills of Muko ore deposits and tests carried out to establish their composition and properties. X-ray diffraction and scanning electron microscopy were employed in the investigation and chemical analysis performed to determine the compounds constituting the ore. The quality of this ore was compared to generalized world market standards and ores from other nations. It was found that Muko ore is a rich hematite grade with Fe content above 65%. It has little gangue (<6% SiO 2 and 3-4% Al 2 O 3 ) and low contents of the deleterious elements (P ∼ 0.02% and S < 0.006%), which correspond to acceptable levels for commercial iron ores.

“…In the flotation tailing 2 the presence of magnetite and hematite was also identified, as well as negative values of susceptibility to high temperatures due to the presence of quartz. In the flotation tailing 1, a great geometric similarity of the heating and cooling curves is observed, evidencing a reversible curve 7,8 .…”

The characterization of materials is an area of extreme importance for engineering, it uses a range of instrumental techniques to provide an information bank for material analysis and selection. In the treatment of iron ore the mineralogical characterization is done, almost exclusively, by optical microscopy. However, materials with very fine granulometry, below 4 μm, make their preparation and visualization restricted in this equipment. The present work aims to identify the minerals Hematite, Magnetite and Goethite in samples of tailings from the iron ore processing, employing a Bartington MS3 that evaluates the magnetic susceptibility as a function of the temperature. These measurements make it possible to identify Curie temperatures characteristic of Magnetite (580 °C) and Hematite (675 °C), as well as Goethite's Neel temperature (120 °C). The results showed that the application of the technique is of great value for the identification of the magnetic bearing minerals and the quantification of the magnetic potential of the sample.

“…A good example is the Nigerian iron ore mining company (NIOMCO) processing plant at Itakpe, Nigeria which is presently losing a significant volume of its iron minerals to the waste stream as a result of the cost implications of processing the ore beyond the present number of stages. For instance Table1 shows the grades of tailing materials (iron mineral composition) of the NIOMCO processing plant compared with some from other processing plants around the globe [5]. A critical comparison of the content of the table shows that the number of process stages in the Nigerian plant may have been limited to the existing stages in order to limit process cost.…”

Every mineral processing plant flowsheet is selected from several possible alternatives because an ore may be processed using a number of recovery techniques. The flowsheet that is finally selected must have certain technical or economic advantages over the others. In a redesign process of the Nigerian Iron Ore mining Company (NIOMCO) processing plant, Itakpe, five design options (described here as New Design Options A, B and C and Improved Existing Plant Options A and B) were developed as alternatives to the existing plant. Concentrates' properties, recovery ratio or efficiency and efficiency ratio are the technical parameters used as measure of plant performance. The properties analyzed for comparism include iron mineral content of the concentrate, total concentrate weight, concentrate grade, percent recovery and loss. The analyses were done by stepwise iteration of all streams in the flowsheet from comminution to the final concentrate. The results of the analyses show that the concentrate that has the best value for the new iron ore plant options is that produced by the new plant design option C (which employs floatation as the only recovery process) which has a concentrate grade of 70% iron mineral content representing a recovery of 95% and a loss of 5% respectively. This gives the best overall performance.
