iron ore mining and processing methods

Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted Iron ore mining is classified into two categories manual mining and mechanized mining methods Haematite and magnetite are the most commonly found iron ore minerals Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the
