Iron sits near the bottom of the 2015 British Geologic Survey's Risk List, but still made the list given its ubiquitous use in modern society where it is estimated that each person uses between 2000 and 14,000 kg, from the cars we drive and the structures we drive on to the buildings we live, work and play in. Though a very paultry amount by ...

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. Though if this source for …

Iron ore tailings were also used in other concrete applications. For example, Das et al. [13] studied the use of IOT to develop ceramic tiles and their study showed, that tiles produced at a maximum of 40% of IOT were superior in terms of scratch hardness and strength, compared to European standard specifications. In a related research, Yao et al. [14] produced a novel …
