PROCESS FOR BENEFICIATING MAGNETITE IRON ORE - UNIV. OF ...

Magnetite (Fe 3 O 4) (molecular weight 231.55 ) contains 72.36 percent iron. Even if all of the iron appeared as magnetite, no more than about 34.5 to 48.4 percent of the ore would consist of magnetite. Since industrial concentration of this ore is accomplished with magnetic separators, only the iron occurring as magnetite can be recovered.

Magnetite: South Australia's potential

Magnetite ore and processing. A general processing circuit for magnetite ore is initial crushing and screening of run of mine (ROM) ore to <6 mm. The ore is then milled to a specified grind size to liberate the iron minerals from the gangue, then processed further to produce a magnetite concentrate, commonly by a wet magnetic separation process.

Grinding - Mineral Processing

The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.

The Braemar - Magnetite Mines

Braemar ore deposits are unusually soft and only slightly abrasive when compared to typical taconite or BIF deposits. The Braemar deposits therefore offer competitive grinding cost advantages. Braemar magnetite grains occur in a matrix of soft siltstone and shale and break readily along grain boundaries.
