Feb 01, 2020#0183;#32;The main chemical components of iron ore tailings in ANSTEEL were Fe and SiO 2. Hematite, magnetite, quartz and a small amount of chlorite were the major phases in the iron ore tailings. The total iron content reached %, and the chief ferrous minerals in the tailings were hematite (Fe 2 O 3), magnetite (Fe 3 O 4) and carbonate (FeCO 3). (2)
Keywords: Iron Ore Tailings, Pozzolana, Compressive Strength, Workability, Regression Models 1. Introduction Nigeria is a fast developing nation blessed with abundant mineral resources. With major economic developments in the country, more minerals are in demand and thereby, increasing the mining activities. Itakpe iron ore deposits in Ajaokuta,

S#233;etec. The filler is iron ore tailings in particle form and approximately irregular in shape with particle sizes 150, 212 and 300 #181;m from iron ore beneficiation plant in Itakpe, Kogi State in the Middle belt region of Nigeria. Iron Ore Tailings Preparation . The iron ore tailings was dried at
Nov 10, 2020#0183;#32;The addition of iron ore tailings enhances the compressive strength and impermeability of UHPC mortars due to the filling effect of IOT and the pozzolanic reaction of part of the finer IOT when the substitution rate is no more than 40%. The replacement ratio of 40% shows the best results, with low permeability and the maximum compressive strength.
Aug 29, 2015#0183;#32;The overall weak transcriptional responses to shortterm exposure to Lilaflot D817Mcontaining ironore tailings suggest that the mining chemical has relatively low toxic effect on fish. The underlying mechanisms behind the observed CYP1A induction should be studied further.

Elemental analysis of Itakpe Hematite by Energy Dispersive X carried out. The iron ore contained the following: Fe (%), Zn(%), Ca(%), Cr(%), Mn(%), Nb(%) and V(%) respectively. The study opines that the hazards to human health caused by exposure to
Chemical analysis of Itakpe: Table 1 shows the analytical results of the Itakpe iron ore chemical compositions. This was determined with the use of the X Ray Fluorescence (XRF) methods. The experiments were performed at the laboratory of the Tshwane University of Technology, South Africa [2]. XRay Diffraction (XRD) on Itakpe iron ore:
Iron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate. In this paper, iron recovery from IOTs was studied at different points during a process involving preconcentration followed by direct reduction and magnetic separation. Then, slagtailing concrete composite admixtures were prepared from highsilica residues.
Nov 10, 2020#0183;#32;Iron ore tailings (IOT) are mining waste obtained during the beneficiation process to concentrate iron ore, . The discharge capacity of tailings in China increases every year, accounting for more than 50% of the world''s tailings discharge.

Mar 04, 2014#0183;#32;Abstract. An evaluation of the Itakpe iron ore tailings (IOT) for concrete production has been carried out using the material to replace sand and cement, in proportions of 5 % up to 30 %, and curing for periods 90 days in water. Characterization of the material showed that it has pozzolanic properties, and can be used as a retarder for hotweather concreting.

Therefore, the crude sample of Itakpe Iron Ore dumped tailings is a haematite rich mineral and has been found to be coarsely packed and interlocked with magnetite and silica with silica as major impurity. However, easy liberation was facilitated by communition due to the coarsely packed nature of ore matrix.
The bulk ore used in this study was obtained from the Itakpe mine, north of Okene in Kogi State, Middle Belt Region of Nigeria. Its chemical composition as revealed by Xray fluorescence is as shown in Table1. TABLE 1: Chemical Composition of Itakpe Iron Ore Mineral Fe2O3Fe3O4SiO2CaO Al2O3MgO TiO2.
Mar 02, 2010#0183;#32;Iron ore tailings (IOT) are mining and mineral waste from the iron ore mining industry. In Nigeria, the Itakpe and Agbaja iron ore deposits have generated a large amount of impurities. The Itakpe iron ore is haematite rich; this mineral being intergrown with magnetite and silica as its major impurity.
The Itakpe Iron Ore Mine was divided into four benches; 241 258 m, 263 275 m, 276 286 m and 308 312 m. Joints along the discontinuities were mapped. The data obtained were analyzed using
