In this study it was found that highly energy-efficient autogenous processing routes can offer significant benefits for fine-grained, competent magnetite ores. The traditional AG mill and pebble mill-style comminution circuit or those requiring significant steel grinding media to operate have been found to be less effective from a purely economic perspective.

magnetite iron ore crushing processing flow chart

The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH ...

Beneficiation of Magnetite Ores - MDPI

magnetic classification [2], magnetite ores require extensive beneficiation to produce iron concentrates. This is because most magnetite ores are fine-grained and mineralogically complex, require fine and ultrafine milling (usually finer than 45 m) [3] to su ciently liberate the magnetite mineral from the predominantly silica gangue.

01-01-2015  While magnetite is naturally suitable for magnetic separation, oxidized iron ores are much more difficult to recover using magnetic separators, because their magnetic susceptibilities are only about 1% of that for magnetite. Of the oxidized iron ores, specularite is most susceptible to magnetic fields, as it is better crystallized, followed by ...

Magnetite - Wikipedia

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite
