If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite, and quartz.
Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used.
Sep 16, 2013· 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. Beneficiation of iron ore is ultimately guided by this inherent mineralogy as well as secondary ...
Three minerals with stoichiometric Ti-content have been identified in the Kiirunavaara iron ore deposit: titanite, ilmenite, and rutile. Ilmenite and rutile are the major Ti-bearing minerals in Fe-rich and P-poor parts of the ore deposit, whereas titanite is predominant in the zones with slightly lower Fe-content and higher SiO2-content.

In mining, gangue (/ ɡ æ ŋ /) is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit.It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is rock already stripped of valuable minerals.

Beneficiation of iron ore is ultimately guided by this inherent mineralogy as well as secondary
As nouns the difference between ore and gangue is that ore is rock that contains utilitarian materials; primarily a rock containing metals or gems which -- at the time of the rock's evaluation and proposal for extraction -- are able to be separated from its neighboring minerals and processed at a cost that does not exceed those materials' present-day economic values while gangue is...
The mineral deposit is not only related to ore minerals. They always have valuable minerals with them. These are called gangue minerals. An ore deposit rich enough to work with profits is called an ore deposit and is called ore minerals plus gangue ore in an ore deposit. Vein-Mineral-Deposits. Note.
Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore.
