The iron oxide mineral magnetite as Fe 3 O 4 has a mass percent of 72.36% Fe and 27.64% O and typically occurs as a natural ore containing 15–40% Fe. Historically hematite direct shipping ore (DSO) has been the preferred source of iron ore globally, with significant resources located on several continents, including Australia in the Hamersley Range, Western Australia.

goethite and hematite in tailings. Again an attempt was made in 2010 by conducting in-house and external study to recover escaped iron ore bearing minerals from ultra-fines recovery plant on line tailings using column flotation and wet high intensity magnetic separators. However the WHIMS process is

technologies, namely the wet magnetic separation, allows the processing of magnetite quartzites only, while oxidized iron ores are refused. The annual losses of iron (hematite) with tails of wet magnetic separation in the processing of the concentrated magnetite quartzites is over 2.0 million tons just on a single production facility.

1. Introduction. Hematite (α-Fe 2 O 3) is widely distributed in various rocks and is one of the most common and abundant iron oxide minerals in soil (Zhang, 2007).However, it cannot be used in iron and steel industry without preliminary beneficiation due to its low grade. Many researchers have investigated the separation of iron minerals from gangue minerals by …

Magnetic separation using wet high-intensity technique has become one of the most suitable methods for recovery of iron from low-grade ores [6], due to …

The most valuable minerals are Hematite and Goethite and main gangue minerals are Calcite and Quartz. Wet and dry high-intensity magnetic separation methods were applied for processing. The full factorial design was implemented for all of the wet high-intensity magnetic separation (WHIMS) experiments. Factors

A high magnetic field allows separation of non-magnetic material to tailings. Magnetic material remains as a concentrate and is transferred to the primary grinding plant. The primary grinding plant of four ball mills grinds the ore in slurry into fine particle sizes of <50 µm before further magnetic separation to produce a concentrated ...

Crude ores in which most of the recoverable iron is magnetite (or, in rare cases, maghemite) are normally concentrated by magnetic separation. The crude ore may contain 30 to 35 percent total iron by assay, but theoretically only about 75 percent of this is recoverable magnetite. The remaining iron is discarded with the gangue.
