Mining of Iron Ores IspatGuru

2014-3-14  The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.

Collections: Iron, How Did They Make It? Part I, Mining

2020-9-18  Instead, iron was generally mined in simple open-pit mines or trenches (if following a shallow vein), using a mix of fire-setting and iron hand-tools. There are some instances of more complex works chasing veins of particularly rich iron ores; my understanding is that there was Roman underground mining of iron in Noricum, for instance, after c. 15 B.C. or so.
