>The extraction of vanadium from titanomagnetites and other sources
Vanadium does not form concentrated deposits like other metals such as copper, nickel or zinc. It is widely dispersed in the Earth's crust, with V 3+ replacing Fe 3+ or Al 3+ in a number of minerals. Vanadium as V 3+ can substitute for Fe 3+ in magnetite (Wenk and Bulakh, 2004); vanadium(III) and iron(III) ions have near identical ionic radii …
>Iron Ore
Mining and processing hematite and magnetite ores. High-grade hematite ore is referred to as direct shipping ore (DSO) as, once mined, the ore goes through a simple crushing and screening process before being exported for steel-making. Australia's hematite DSO from the Hamersley province averages from 56% to 62% Fe.

A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding. The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic …
>Hematite vs Magnetite: Unveiling the Differences in Iron Ore
Hematite, which is primarily found in banded iron formations, has a lower iron content than magnetite. However, it is easier to process due to its softness and can be extracted through open-pit mining or underground mining methods. Additionally, hematite does not require as much energy during processing as magnetite does.
