Iron Ore Iron Species and Gangue Mineralogy Mapping

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

Gangue Mineral an overview | ScienceDirect Topics

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.

Word to the Wise

Because of the abundance of iron in the earth's crust (rough-ly 6 percent) pyrite, FeS,, is associated with almost all sulfide ore deposits. However, it is rarely of economic importance and thus is often a gangue mineral. Pyrite is also a common gangue mineral in coal deposits. In mine development most gangue minerals end up on the waste pile.
