The Behavior of Itakpe Iron-Ore Tailings in One-dimensional ... 1The Federal University of Technology, Akure, Nigeria Corresponding author email: [email protected] ABSTRACT Tailing dam failure can be so hazardous and result in irrevocable environmental impacts. In recent years, more attention has been paid to the mechanical behavior
The Itakpe iron ore processing plant in Nigeria presently produces a tail sometimes containing up to 22% iron minerals mostly natural fines in the ore and fines produced inevitably during comminution.
Samples of Itakpe Iron Ore waste dump (tailings) were collected using random sampling method from different locations at the tailings dump sites of National Iron Ore Mining Company (NIOMCO) in Itakpe, Kogi State, Nigeria and properly homogenized to give the head sample.

One of such mineral in Nigeria is Iron ore. There are over 3 billion tonnes of iron ore found in Kogi, Enugu, Niger, Zamfara and Kaduna States. The large deposit of oolific iron ores of Kogi and Enugu States are yet to be fully explored. Iron ore is used for making steel, transformer and motor cars, ferrous sulphate from waster liqueur of the ...
Millions of tons of iron ore tailings (IOT); a by-product of iron ore processing, are disposed of every year in landfills, quarries, rivers, oceans among others thereby posing …
wastes or tailing dumps in abandoned mines also pose contamination risks to the environment and human health [4]. Itakpe iron ore mine situated within longitude 6 016 E and latitude 7 36 0N and 7 39 N of the equator (Fig. 1)is among the largest reserves in Nigeria and ranked as one of the best in the world having estimated reserves of 3 billion
China generates 1.5 tons of iron ore tailings for each ton of iron ore concentrate.21,22 In this country, the annual production of iron ore tailings reaches about 180 million tons and is increasing.23 In India, between 10-12 million tons of iron ore tailings are extracted in the form of ultrafine waste.24 In Australia, it is estimated that ...
The iron ore tailings aggregates concrete exhibited a good mechanical strength and even in the case of compressive strength, there was an improvement of 11.56% over conventional aggregates concrete. The indirect tensile strength did not improve against the control mix due high content of fines in the tailings aggregates but showed 4.8% ...
During the iron minerals extraction from BIF, two types of non-economical tailing materials called generically iron ore tailings (IOT) are generated, i.e., a coarse tailing, generated in the flotation stage, consisting mainly of quartz, and a fine tailing, whose main components are usually quartz, hematite, goethite, and kaolinite.
The study was aimed at the evaluation of the effect of iron ore tailings as an admixture in cement stabilization of lateritic soil. Air-dried soil was treated with ordinary Portland cement (OPC) – iron ore tailing (IOT) blend in stepped concentration of 0, 2, 4, 6 and 8 % by dry
The concentration of metals in the tailings of Ife/Ijesa goldmine, Nigeria was identified by using Proton Induced X-Ray Emission spectrometry as the main analytical tools. ... 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 ...
Itakpe Fe ore in Nigeria produces about 36% ore on average from 200 million tons. The Itakpe project was built and designed to treat a minimum of 24,000 tons/day and operated 300 days/year. ... Therefore, iron-ore tailings within the African continent can serve as potential future research by converting the waste into wealth and provide a ...
Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, the global annual …
The iron ore tailing (IOT) used for this work was sourced from Itakpe Iron Ore processing plant in Ajaokuta, Kogi State, Nigeria, and was designed to supply 2.15 million …
The aim of this research is to evaluate the use of iron ore tailings aspartial replacement of filler in the production of asphalt concrete for highway construction. The objectives of this study are as …

Engineers can gain from improving the soil by adding fibres, Iron Ore Tailings, and other elements. With a rise of 0.20% PPF to 0.60% and a constant 10% dose of Iron Ore Tailings by the weight of soil, numerous tests are conducted on …
The Itakpe iron ore processing plant in Nigeria presently produces a tail sometimes containing up to 22% iron minerals mostly natural fines in the ore and fines produced inevitably during comminution.
Iron ore tailings (IOTs) are a byproduct of the iron ore beneficiation process and are a significant source of solid waste [13, 14].In China alone, an astounding 600 million tons of IOTs are produced annually, yet the utilization rate remains shockingly low at only 7% [14].The high demand for iron production has led to an increased disposal of IOTs, resulting in severe …
2.1.3 Iron ore tailing Iron ore tailing having bulk density 1594 kg/m3 and fineness modulus 2.53. The specific gravity was found to be 2.85.The particle size distribution is plotted as shown in fig 2. The gradation of tailing used, is partly within limits specified in ASTM C 31.
Iron ore tailings (IOT), the predominant solid by-products of iron ore mining and refining, present significant environmental challenges due to their sheer volume. This paper endeavors to scrutinize the prospective deployment of IOT as an alternative to soft soil in the fabrication of controlled low strength materials (CLSM) for backfill applications.
This study investigates the behavior of iron ore tailings obtained from Itakpe, Kogi State, Nigeria, in an incremental oedometer loading. The samples were prepared by different methods and ...
Engineers can gain from improving the soil by adding fibres, Iron Ore Tailings, and other elements. With a rise of 0.20% PPF to 0.60% and a constant 10% dose of Iron Ore Tailings by the weight of soil, numerous tests are conducted on black cotton soil. The final strength level is reached at 0.4% PPF and a constant 10% Iron Ore Tailing dosage.
Iron ore tailings are the materials left over after the beneficiation process of separating the valuable fraction from the worthless fraction of an iron ore. Itakpe iron ore deposits in Ajaokuta, Kogi State, Nigeria, is where such mining activities are going on, and has a total estimated
