An overview of the beneficiation of iron ores via reverse

2014-3-10  Iron is one of the most common elements in Earth's crust. The primary industrial types of iron-bearing minerals include oxides and hydroxides and, to a lesser extent, carbonates: magnetite [Fe 3 O 4], hematite [Fe 2 O 3], goethite [FeO(OH)], limonite [FeO(OH) × nH 2 O] and siderite [FeCO 3].The genesis of iron ore deposits is variable, similar to numerous other ore types.

Froth flotation of iron ores AMERICAN CYANAMID CO

This invention relates to the beneficiation of iron ores by froth flotation. More particularly, the invention relates to a two-stage flotation process suitable for use on fines such as are found in the overflow from iron ore washer plants; in waste products from heavy media separation processes and on those ores which must be finely ground in order to unlock the iron minerals from the gangue.

Collecting Agent–Mineral Interactions in the Reverse

Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides. Nowadays, reverse flotation is the most commonly used route in iron ore flotation. This review is focused on the reverse flotation of iron ores, consisting of reverse
