Special Issue Information. Dear Colleagues, Iron ore flotation is a key technique to concentrate intermediate-low-grade ore, in order to reach the market requirements for higher-grade concentrates of iron. The presence of some impurities in addition to quartz in iron ore, aluminium silicates, and minerals containing phosphorus impair ...
Iron ore direct reduction is an attractive alternative steelmaking process in the context of greenhouse gas mitigation. To simulate the process and explore possible optimization, we developed a systemic, multiscale process model. The reduction of the iron ore pellets is described using a specific grain model, reflecting the transformations from hematite to iron.
For example, the preparation of iron ore tailings (IOT) concrete can effectively alleviate the contradiction between resources and the environment [11-16]. After long-term use at high temperatures, the IOT reinforced concrete will suffer from problems like carbonization, corrosion, and durability decline, and even engineering safety risks.

Iron ore is the primary raw material from which metallic iron is extracted to make steel. The rapid increase in crude steel production in the last decade has seen major expansions in world iron ore production from around 1 billion tonnes (Bt) in 2001 to over 2.9 Bt in 2012.
The price of iron ore has fallen roughly 40% since mid-July on concerns about demand from China, dealing a blow to producing countries such as Australia and Brazil that are battling to protect ...

passes through the district. Iron ore formations occupy most part of the district which can be traced from the Jharkhanda Border in the North to the Jajpur district boarder in the South of the district. According to Indian Bureau of Mines, 2005, the Keonjhar district itself contains 75% of the iron ore reserves of Orissa. The number

The strength of the filling body is largely affected by the properties of the binder, mineral composition, fineness, and slurry concentration of tailing. In this paper, the rheological test was conducted to determine the slurry concentration of iron ore tailing containing gypsum. Then, the samples made from slurry and three binders, Portland cement, filling plant binder, …

The cement industry has for some time been seeking alternative raw material for the Portland cement clinker production. The aim of this research was to investigate the possibility of utilizing iron ore tailings (IOT) to replace clay as alumina-silicate raw material for the production of Portland cement clinker. For this purpose, two kinds of clinkers were prepared: …
In the iron ore industry, it is utilized as a binder to produce iron ore pellets, since it improves ballability (Qiu et al., Reference Qiu, Jiang, Fan, Zhu and Huang 2004) and the strength of as-prepared wet green pellets (Forsmo et al., Reference Forsmo, Apelqvist, Bjorkman and Samskog 2006) and of dried pellets (Volzone & Cavalieri, Reference ...
Iron ore fines are characterized on a physical basis by variations in particle size, shape, density, porosity, surface area, roughness, and wettability. Furui et al. (1977) divided iron ore particles into nucleus particles of +0.7 mm, intermediate particles of …

In this study, the effect of the radial charging position on the reducibility of acid iron ore pellets was investigated using a laboratory-scale, high-temperature furnace in CO-CO 2-N 2 and CO-CO 2-H 2-H 2 O-N 2 atmospheres up to 1100 °C. The experimental conditions were accumulated based on earlier measurements from a multi-point vertical ...

The porosity of iron ore tailings geopolymer bricks ranged from 14.6% to 25.4% and for red mud geopolymer bricks ranged from 14.28% to 36.4% (Figure 11). This has not shown the significant influence on the compressive strength. The density of brick has not been significantly influenced by the varying percentages of iron ore tailings and red mud.
