Ironmaking is a multi-step process in which iron ore (hematite, Fe 2 O 3) is oxidized first into magnetite (Fe 3 O 4) and then to an intermediate material known as wüstite (Fe 1-x O) before it can be refined into the pure iron (Fe) suitable for steelmaking. The challenging step, the team reveals, is the transition from wüstite to pure iron.

Abstract. In order to minimise the environmental, social and economic impacts caused by the mining activity, this work proposes the use of iron ore tailings from tailings dams (IOT) as pigment in the production of a paint for buildings – the Sustainable Paint. The waste originates from the mining activity in the state of Minas Gerais.
The ore-to-overburden ratio for surface mining is generally around 1:5 to 1:2 depending on local situations (Feng et al., 2021, Yellishetty et al., 2008).In 2008 and 2009, about 75 % of overburden materials and 25 % of tailings were generated as solid residues in Minas Gerais, Brazil (Schatzmayr Welp Sá et al., 2022).However, to the best of the …
With the development of urbanization, the demand for bricks continues to increase. However, traditional brick production methods result in significant energy consumption and environmental pollution. In Hebei Province, China, historical mineral extraction activities have left behind substantial iron ore tailings (IOT). With the objective …
A hydrogen-based direct reduction of iron ore (DRI) and steel scrap melting in an electric arc furnace (EAF) appeared to be the most mature technological routes to date, capable of reducing CO 2 emission by 95% but rely on the availability of rich iron concentrates as feed materials. Shaft furnace technologies are the common DRI-making …
By helping steelmakers curb their greenhouse gas emissions, iron ore miners can advance their own decarbonization efforts. Decarbonizing steel production, …
With the goal of addressing these issues, the researchers launched a 12-month study and independently sampled and investigated sand produced from iron ore mining, pioneered by Vale S.A in Brazil.
Iron ore is essential in steel making; however, high-grade ores have diminished, making low-grade ores inevitable. These low-grade iron ores need further beneficiation to upgrade the iron content. Currently, traditional physical and chemical methods are utilized and are not environmentally friendly. Bio-beneficiation techniques …
A Pilbara iron ore mine that experienced 'boom-time' growth in the mid to late 2000s needed ways to reduce maintenance costs when the price of iron ore plummeted. It was suffering the effects of an inefficient and limited maintenance strategy, thanks to hastily compiled work management master data and a rushed implementation of the CMMS ...
