This International Standard specifies an EDTA photometric titration method using fusion decomposition for the determination of the total iron content of iron ores This method is applicable to a concentration range of 37 00 % to 72 00 % m/m of total iron in natural iron ores iron ore concentrates and agglomerates including sinter products
·Iron Ore Iron ores are rocks and minerals from which metallic iron can be extracted ; India has large iron ore reserves It occurs in various geological formations but major economic deposits are found in volcano sedimentary Banded Iron Formation BIF from the Precambrian age ; Magnetite is the finest iron ore with a very high content of iron
Iron ores are rocks and minerals from which metallic iron can be extracted There are four main types of iron ore deposit massive hematite which is the most commonly mined magnetite titanomagnetite and pisolitic ironstone
·Iron ores are commonly described throughout the international iron ore industry in terms of decreasing relative physical hardness from hard to medium friable and finally powder or dust Figure Hardness is clearly independent of mineralogy alone with for example hematite only ores varying from powdery to very hard Ores that are of
5 ·The principal ores of iron are hematite ferric oxide Fe 2O 3 and limonite ferric oxide trihydrate Fe 2O 3·3H 2O Other ores include siderite ferrous carbonate FeCO 3 taconite an iron silicate and magnetite ferrous ferric oxide Fe 3O 4 which often occurs as a white sand Iron pyrite iron disulfide FeS 2 is a crystalline gold
Direct reduction in which iron ores are reduced at temperatures below the metal s melting point had its origin in such experiments as the Wiberg Soderfors process introduced in Sweden in 1952 and the HyL process introduced in Mexico in 1957 Few of these techniques survived and those that did were extensively modified
·Iron ore pellets are made from both magnetite and hematite ores Hematite ores are concentrated using a flotation process Pellets include a mineral binder that represents about 2% by weight
·A novel stepped flotation technique is discussed for the treatment of carbonate rich iron ores The necessity of desliming to enable effective flotation is discussed in detail Selective
