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.

Beneficiation of Iron Ore - 911 Metallurgist

Mar 19, 2017 . This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500-mesh for liberation of the iron minerals from the.

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.
