    iron ores are less rich and have a large number of impurities. The most important iron ore-forming minerals are: • Magnetite - Magnetite (Fe3O4) forms magnetic black iron ore. There are large deposits of magnetite in Russia and Sweden. • Hematite - Hematite (Fe2O3) is a red iron ore. Hematite occurs in almost all forms, from

    Ore Dilution & Recovery in Mining

    Apr 05, 2017 Under the conditions on the Gogebic iron range, Michigan, where much of the capping carries 40 percent or more iron, a small amount of dilution does not seriously affect the grade of ore mined and the dilution from this source may offset tonnage of ore lost; the net result is therefore likely to be approximately 100 percent tonnage recovery, with a slight lowering of

    In India we get four types of iron ores, viz. (a) hematite (Fe 2 0 3 ), magnetite (limonite (2Fe 2 0 3 .3H 2 0), and siderite (Fe 2 C0 3 ). The hematite ore or red-ochre is called ‘ox ide of iron’. It has ferrous content ranging from 60 to 70%. It is mainly found in the Dharwad and Cuddapah rocks of the Peninsular India
