Iron ore - Wikipedia
Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and ...

NATURAL RESOURCES SUSTAINABILITY: IRON ORE …
The energy used to release low-grade iron ore is greater than the demands of a DSO. Nevertheless, at times, DSO does not have a high grade after mineral processing. Figure 1. Iron ore grade and CO 2 emissions . Therefore, an exponential function was adjusted to reflect the relationship between CO 2 emissions and iron ore grade.
Advances in Low Grade Iron Ore Beneficiation
iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This stone deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.

Iron processing - Ores | Britannica
Iron processing - Iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is ...
