Iron processing - Ores, Smelting, Refining Britannica
Concentrates. Upgrading. 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.
