The Triumvirate: Coal, Iron, and Steam – Creatures of Thought
Later, engines were used to blow fresh air into the shaft and to lift ore to the surface, in mines of all types, including iron mines. Then the coal produced from the mine went on to be used as fuel to smelt iron, with the help of other steam engines to power the bellows. Some of that iron went into the construction of more steam engines.

High coking coal prices provide glimpse into steelmaking's future
Higher-priced coking coal is likely to affect the steel industry's transition to greener production methods as well as the value-based pricing of iron ore. Higher-priced coking coal increases the cost of producing steel via blast furnaces, both in absolute terms and relative to other routes. This typically leads to higher steel prices as raw ...

Ancient Mining Tools and Techniques
In Northern and Northeastern Europe, bogs were the site of bog iron, the earliest form of iron used for tools. Iron compounds from plant decay precipitate out and are deposited at the bog bottom. These nuggets of iron were harvested and smelted to produce mining tools of wrought iron. Some people harvest iron in this manner to this day.
