Steel slag is an industrial waste that is generated during the production of steel. In the production of steel, oxides of metal impurities in the iron combine with the flux (which is …
The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is red; magnetite (Fe3O4), which is black; limonite or bog …
Iron-containing waste is constantly accumulating and increasing the use of low-grade ores only accelerates this process. Such deposits lead to a number of environmental and land-use problems and …
Solid waste management is a critical issue worldwide. Effectively utilizing these solid waste resources presents a viable solution. This study focuses on Iron ore tailings (IOTs), a solid waste generated during iron ore processing, which can be used as supplementary cementitious materials (SCMs) but have low reactivity, hindering their large-scale …
Research shows that when iron tailings powder is mixed with slag powder, concrete has relatively good mechanical properties (Wu and Liu, 2018; Han et al., …
Direct Reduction processes for iron ore employing natural gas or hydrogen are becoming more important. Correspondingly, properties of outgoing products are of …
Iron Ore Tailings (IOT) are the waste slag resulted from iron ore mines. Large amount of Iron Ore Tailings (IOT) have been generating every year posing serious environmental problems, large production of cement …
Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight. At the mine site, the taconite ore is ground to a fine powder, and strong magnets are used to separate magnetically susceptible particles containing magnetite and hematite ...

Author keywords: Engineered cementitious composites; Sustainability; Tensile ductility; Iron ore tailings. Introduction Iron ore tailings (IOTs) are large piles of ground rocks that are discarded during the beneficiation process of iron ore concentra-tion. In rapidly developing countries like China, the generation of IOTs has been increasing ...
Iron filings are considered waste products produced from metalworking processes as small pieces of iron that look like fine powder. In this research, the landfill is the method of dealing with this waste.
For example, the iron and steel plants, fertilizer industries, and chemical, drug, and dye industries produce silver foil, plastics, fly ash, gypsum, synthetic fibres, …
subsequent bene˜ciation processes, the iron ore is in a ˜ne powder form. This cannot be used directly as feed material for iron-making processes and is processed using agglomeration or sintering to produce iron ore pellets with suitable physical characteristics for feed to a blast furnace. Once bene˜ciation and processing are
Incorporating waste by-products in concrete is one of the critical approaches for sustainable development. Particularly, iron ore tailings (IOT) as ordinary industrial solid waste in China is ...
Due to the rapid increase of pollution around the world, the disposal of waste materials such as granite powder (GP), iron powder (IP), brick powder (BP), and waste plastic particles (PP) is a ...
The obtained properties of these fluxed pellets were compared with the properties of iron ore lump and pellets, which are being used conventionally in the blast furnace for production of iron and steel. ...
