Rock-to-Metal Ratio: A Foundational Metric for Understanding Mine
The quantity of ore mined and waste rock (i.e., overburden or barren rock) removed to produce a refined unit of a mineral commodity, its rock-to-metal ratio (RMR), is an important metric for understanding mine wastes and environmental burdens. In this analysis, we provide a comprehensive examination of RMRs for 25 commodities for 2018. The results …

Extracting hydrogen from rocks
Geologic hydrogen, as it's known, is produced when water reacts with iron-rich rocks, causing the iron to oxidize. One of the grant recipients, MIT Assistant Professor Iwnetim Abate's research group, will use its $1.3 million grant to determine the ideal conditions for producing hydrogen underground — considering factors such as catalysts ...

Collections: Iron, How Did They Make It? Part I, Mining
Bog iron is much easier to smelt because it contains fewer impurities than iron ore in rock deposits, but the quantity of iron available from bog iron is relatively low (although actually renewable, unlike mines; a bog can be harvested for iron again after a few decades as the processes which produce the bog iron continue).

First, it unleashes acid, dissolving surface minerals to get to its food. Then, it releases chemicals that extract that food—in this case, iron. Finally, its fast-growing fungal filaments cut into the remaining rock like a knife, carving deep channels that break up iron-depleted surfaces and expose fresh layers for consumption.
