Accurate prediction of mineral grades is a fundamental step in mineral exploration and resource estimation, which plays a significant role in the economic evaluation of mining projects. Currently available methods are based either on geometrical approaches or geostatistical techniques that often considers the grade as a regionalised …

In summary, we developed an S-HGMS with coupling with acid leaching technology for recovery and preparation of high-grade silica from high‑silicon IOTs. Firstly, iron ore was mined and then processed to obtain iron concentrate and high-silica IOTs by the process of crush–grind–screening–gravity separation–magnetic separation [72]. The ...

In this study, the low-grade iron ore is investigated as a potential source for alternative steel-making by carbothermal reduction. The heating effect of micro-wave on naturally occurring low-grade iron ore is investigated and is compared with the synthetic mixture of analytical grade iron-oxide and quartz for the first time in this study.

This research is based on the iron smelting workshop evidence recorded at the SBAC (Figure 2). Excavations revealed iron ore as the raw material of iron smelting, iron slag and iron ingots, tuyeres and base of furnace. The existence of a combustion furnace clearly strengthened the interpretation it served as an iron smelting workshop.

Iron mostly exists in the form of iron oxide, e.g. hematite (ferrous oxide). So what you found is mostly likely one of the 16 iron oxides known on earth. Of course the iron used to make our tools in everyday life doesn't come from backyard soil. Instead, iron is more economically extracted in large scale from iron ores using heavy equipment.
