Metal ore mining in Europe

Since the iron ore is extracted in underground mines (Fig. 2), mining costs are hardly competitive compared to the open pit mines of, for example, Australia or Brazil. As a consequence, the low iron ore prices have been very problematic for mining companies. Northern Iron, which operated a mine in Kirkenes in Norway, had to file for bankruptcy in 2015. Northland Resources in .

Life cycle assessment of iron ore mining and processing ...

· Crushing and screening is typically the first step of iron ore beneficiation processes. In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated. This screening is an essential step prior to their separation into ore product and waste rock.
