Mine drainage: Treatment technologies and rare earth …
Iron fillings were evaluated to adsorb antimony (Sb) and arsenic (As) from circumneutral mine drainage in a simple field treatment system of two batch reactors in the former Sb mine in Popro (Slovakia; Sekula et al., 2018). This passively operated treatment system was able to achieve the average removal efficiency of Sb and As at 84% and 89% …

25.1 Exploration: Finding minerals | Mining of mineral …
The first iron mining techniques used charcoal which was mixed with iron ore in a bloomery. When heating the mixture and blowing air (oxygen) in through bellows, the iron ore is converted to the metal, iron. The chemical reaction between iron oxide and carbon is used here to produce iron metal. The balanced chemical equation for the reaction is:

Green steelmaking will need technology and mining advances
To avoid locking in further coal-based steelmaking capacity for decades, some technology switching to DRI-electric arc furnace (EAF) processes will be required before then. Potential new DR-grade iron ore capacity by 2030 ranges from 40 million tonnes per annum (Mtpa) to an optimistic high of 100Mtpa. Unless technology innovations allow …

All the Metals We Mined in 2021: Visualized
Iron ore accounted for 93% of the metals mined in 2021, with 2.6 billion tonnes extracted from the ground. It's important to note that this is ore production, which is typically higher than metal production since metals are extracted and refined from ores. For example, the iron metal content of this ore is estimated at 1.6 billion tonnes.
