What exactly is Mill Scale and what is done about it

2005. A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic blue-gray "steely" color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.


Developments in the physical separation of iron ore ...

The disk magnetic scavenger is used for magnetite scavenging and is usually installed on the combined tailings stream of the magnetite separation plant. It can lower the iron grade of the final tails and thus help to achieve a higher iron recovery. 9.3.2. High-intensity and high-gradient magnetic separators


Magnetite Beneficiation: A Focus on Flowsheet …

tragedies have motivated research into the dry processing of iron ores. In the mineral processing industry, dry magnetic separation is commonly used for removing tramp metals [10] and the coarse cobbing of magnetite ores [11,12]. However, it is ine cient for processing finely ground magnetite ores [7,10].
