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 ...

· Flotation tests conducted on the two Iron Duke samples using oleate showed that the presence of goethite adversely affected the flotation response of the hematite but contact angle measurements showed a higher hydrophobicity for the sample containing 25% goethite. Correcting the oleate addition for the changes in surface area still showed that the goethite reduced the flotability of the hematite.

metamorphic sedimentary iron ores, accounting for about 50% of the total reserves of iron ore, known as the Anshan iron ore. The main iron minerals of which are magnetite and hematite. Gangue minerals are large amounts of quartz and a small amount of silie minerals such as feldspar, mica, pyroxene.
Hematite(week magnetic ore) is refractory minerals. Before, the flotation and roastingmagnetic separating process are mainly used. For the past few years, due to the appliion of strong magnetic separator, undersize sieve etc new equipment and gravity separation equipment, reverse flotation process, hematite (week magnetic ore) dressing have got remarkable effect.
hematite processing by flotation. Direct shipping of high grade iron ore, because of depletion or partial depletion of reserves, or high costs of operation has forced operators to use some means of beneficiation to produce an acceptable product with the lower grade iron ore reserves.
