Iron mining Industrial History of Cumbria

Three miles to the north-west an outlying vein in the Wicham Valley yielded haematite ore from the fault between the limestone and the older Skiddaw slate. Just when mining began is a point open to conjecture. Archaeological evidence determines that ore was smelted in the vicinity of Urswick during the Iron Age by indigenous Celts.

2017-3-27  Extraction of Metals. Extraction of Iron.. Iron is extracted from its ore in the blast furnace.. The main iron ore is called haematite. Haematite is iron(III) oxide - Fe 2 O 3. The iron ore contains impurities, mainly silica (silicon dioxide). Limestone (calcium carbonate) is added to the iron ore which reacts with the silica to form molten calcium silicate in the blast furnace.
