— World is bestowed with self-sufficient magnetite and hematite iron ores. Huge volume of mining waste, namely iron ore tailings (IOT), is generated during processing of iron ore, leading to environmental concerns. At the same time, due to excessive usage and environmental regulations, there is scarcity of naturally available …

In this research, iron ore tailing (IOT) is utilized as the cementitious material to develop an eco-friendly ultra-high performance concrete (UHPC). The UHPC mix is obtained according to the modified Andreasen and Andersen (MAA) packing model, and the applied dosage of IOT is 10%, 20%, and 30% (by weight), respectively. The calculated packing density of …

The research on whether can iron ore tailing improve the compressive strength of alkali-activated slag ing concrete is conducted. The experiment shows that too little or too much powder from iron ore tailing will reduce the compression strength of alkali activated slag concrete, when powder from iron ore tailing achieving optimal amount, the …

Vale (NYSE:VALE) said Tuesday it has created a company that will sell and distribute sand obtained from its iron ore tailings, as it seeks ways to reduce the disposal of waste …

 — Iron ore tailing/slime (-150 m) is produced after scrubbing and wet screening of a low-grade iron ore. Tailing beneficiation of iron ore has been addressed either by flotation or wet high intensity high gradient separation. The present study aims to recover iron values from discarded slime containing assay ~56% Fe, ~6.5% SiO2, and ~7.0% …

 — The exploitation of iron ore requires the construction of dams to dispose of waste after processing it. This residual material is called tailings and the specific physical-chemical characteristics depend on the beneficiation process adopted and vary depending on the main constituents and the presence of trace elements and residual organic …

As far as iron is concerned, even though pyrite contains a sufficient concentration of iron, pyrite is not a leading source of iron production either. Instead, hematite is the leading source of iron ore for economic reasons. …

Studies on tailing slime have been carried out at iron ore mines in Orissa and the results are discussed. The tailings contain toxic elements and find their way into the water environment. Sedimentation test was carried out on tailings and the area required for tailing pond was found to be 3155 m2 in comparison to 10000 m2 obtained from the use ...

 — 1. Introduction. Iron tailings, generated from the beneficiation and metallurgy of iron ore, are hazardous wastes that pose significant environmental challenges due to their large-scale disordered storage, resulting in widespread damage and safety concerns [1], [2].The annual worldwide deposition of over 10 billion tons of iron tailings in tailings …

 — Indian mining industries primarily depend upon high-grade fines mainly because of two factors, one is lack of beneficiation infrastructure and high cost of low-grade fines, the second one is lack of proper tail disposal system. Due to lapses in our policies, miners get better premium by selling high-grade fines over low-grade fines. This restricts …

 — Iron ore tailings, one of the most common solid wastes in the world, are a byproduct of the beneficiation process of iron ore concentrate. The volume of this type of …

 — Iron ore tailings. A number of representative iron ore tailing samples were acquired from different locations of the dry tailing disposal areas (cf. Fig. 2).As illustrated in Fig. 3, the tailings were loosely dumped as piles; thus, their sampling did not necessitate any particular practice and merely involved filling bags with a hand shovel.A total …
