However, the iron ore from Kashenyi hill has lower iron content (about 6l% Fe) and higher gangue content (5% SiO 2 and 6% Al 2 O 3) at low concentration of the deleterious elements (0.02% P and 0.003% S). According to commercial standards for crude iron ores, this ore can be defined as medium-grade ore.
The exploitation of low grade iron ores is possible after enrichment. The low grade iron ores with considerable amount of gangue minerals, e.g. silica, alumina, calcium and magnesium compounds, require concentration. For concentration, iron ore is crushed and ground for liberation before the implementation of separation.

The genesis of these ores is considered as due to a residual concentration of the iron oxides after leaching of the gangue minerals during the Cenozoic weathering. The genesis of the hard high-grade ore is more complex and not well understood.
Mining waste refers both to gangue (waste rock) and to tailings arising in different parts of the production line. Extensive gangue heaps, among other things containing iron and rare earth elements, at old mines in Idkerberget, Bergslagen.
Iron ores of this type are commonly termed the banded iron formation or simply abbreviated as BIF. All ore minerals in these deposits are oxides and hydroxides. The most common iron ore minerals are hematite, lepidocrocite and goethite while the most common manganese ore minerals are braunite, manganite and hausmannite.
Gangue is valueless mineral associated with a valuable mineral that can economically be utilized, which is an ore .e.g. pyrite (FeS2) will be a gangue mineral associated with say sphalerite (ZnS) if the latter mineral can be utilized commercially; likewise, quartz/calcite will be gangue minerals associated with say an ore of copper…

Automated Hyperspectral Logging. The successful development of iron ore resources is fundamentally linked to our ability to accurately identify not only multiple species of iron oxide minerals, but also sub-species, phases (eg. ochreous vs. hard) and associated gangue minerologies.
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy .
The iron ore 3 contains phosphorus and has a gangue. For example, the iron ore 3 comprises between 45 wt% and 60 wt% of iron, and more than 0.6 wt% of phosphorous. In a variant, the method 1 can be applied to iron ores having a phosphorus content lower than 0.6 wt%, for example a phosphorus content between 0.2 wt% and 0.6 wt%.
