Metal ore mining in Europe

2 Iron ore production. The EU has 9 member states producing iron ore, including Sweden, Norway, Austria, Slovakia and Germany. However, Sweden and Norway are the only countries in which significant quantities of iron ore are mined (Fig. 1). The quantities of iron produced from the mined ore have been between 19.1 Mta and 21.8 Mta in recent years.

The Four Main Methods of Mining

 · The solution gets to work and dissolves the ore before being pumped back into the surface to undergo processing. This method of mining allows for the extraction of salts and metals from an ore body without resorting to conventional mining methods such as underground mining. There are plenty of advantages to using in-situ mining.
