· Meanwhile, the average annual growth rate of imported iron ore was 20%. The growth rate of imports was obviously higher than that of selfproduced ore. Since 2000, China's iron ore imports, except a slight decrease in 2010, 2012 and 2015, increased substantially, the annual import grew twice over 35%.

2019 10 22·Concentration or Dressing of the Ore Generally, the ores are found mixed with earthy impurities like sand, clay, lime stone etc. These unwanted impurities in the ore are called gangue or matrix. The process of removal of gangue from powdered ore is called concentration or ore dressing. several methods for concentrating the ores.

· The very fine iron ore product is obtained after the flotation process. In order to be used in the steelmaking process, it should be pelletized. At smaller percentages, it can also be blended into sinter feed and used at sintering units. The iron content of the CSN Mining pellet feed usually exceeds 66%.

· The five largest producers of iron ore are China, Brazil, Australia, Russia and India. These five countries account for about 70 percent of the world's iron ore production. Canada, the United States, and Western Australia are also major mining loions for gold. The world's oceans also hold vast amounts of gold.
Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH).n(H 2 O)) or siderite .
In the following discussion, the applicability of geophysical methods to geoenvironmental studies of ore deposits is reviewed. Details of geophysical techniques are not emphasized; these are covered in standard texts (Society of Exploration Geophysicists, 1966; 1990) and have been summarized in Hoover and others (1992).

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.
