Processes for Beneficiation of Iron Ores | ispatguru
Mar 28, 2015 . Ball mills are the principal means of fine grinding of iron ores. They are tumbling mills like the rod mills, but usually with a smaller length to diameter ratio which ranges up to 1.5. The grinding media is steel balls instead of rods. Grinding efficiency is greatly affected by the classification efficiency and the mill.

Mineralogy and textural impact on beneficiation of goethitic ore .
The type of mineralogical complexity appeared from the characterization studies of the lean grade/goethitic iron ore causes difficulty in beneficiation and . In case of Sample B, presence of goethitic pisoliths and clay within the matrix of goethite indicates the extensive interlocking at very fine size and leads to poor liberation.
Magnetite Iron Ore Design -
ship hematite ores mined from the upper regolith, magnetite deposits require significant beneficiation which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix. Many banded iron formation deposits are very fine grained often requiring a final concentrate grind size P80 of 25-35 µm.
