Abstract. The Nkout West iron deposit of the northern edge of the Congo craton in southern Cameroon forms part of the northwest plunging isoclinal mega fold composed of metamorphosed banded iron formations (BIFs), which have been deformed and metamorphosed, resulting in recrystallized magnetite, quartz and silicates.

The microscopic study under the polarized and reflected light showed that the iron ore consists of silicate minerals (quartz 50% and zircon 1%) and non-silicate minerals (goethite 30%, hematite 7%, magnetite 3%, pyrite 1%, chalcopyrite 1%, blende 3%, galena 3%, scheelite 1% and gold 2%).
1. Introduction. Banded iron formations (BIFs) are marine sedimentary rocks that formed in voluminous amounts during the Late Archean, with a peak of deposition at ~ 2.5 Ga (Klein, 2005).BIFs typically contain alternating magnetite (Fe 3 O 4)- or hematite (Fe 2 O 3)-dominated iron-rich layers, and microbanded iron oxide-bearing silica-rich and iron-poor layers.

Selective Flocculation of Banded Hematite Quartzite (BHQ) Ores The Open Mineral Processing Journal, 2011, Volume 4 47 consists of hematite and quartz as the major minerals. Minor amounts of magnetite, goethite, limonite as well as kaolinite are also present in the sample. The microphotographs of BHQ sample are shown in Fig. (2). Widely varying ...
Apr 09, 2015· Geology, Prospecting and Exploration for Iron Ore Deposits. ... The largest ore concentration is found in banded sedimentary iron formations of Precambrian age. These formations constitute the bulk of iron ore resources of the world. Iron ores occur in a wide variety of geological environments in igneous, metamorphic or sedimentary rocks, or as ...
This study presents the ore texture, mineralogy and whole rock geochemistry of iron occurrence from the Edea North area located at the upper limit of the Nyong Unit, part of the Congo craton. This iron mineralization is of magnetite quartzite type enclosed by metamorphic rocks of the granulite facies. Two main facies have been identified over the study area including the banded and the massive ...
By far, the two most economically important iron ores are hematite and magnetite. Although hematite is more abundant than magnetite, magnetite has the higher iron content, so magnetite iron ore deposits are highly sought after.
