Iron processing - Ores | Britannica

Crushing and screening are straightforward mechanical operations that do not alter an ore's composition, but some ores need to be upgraded before smelting. Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material.

Magnetite & Lodestone | Mineral Photos, Uses, Properties

Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.
