The Sanaga iron ore prospect is a recent discovery in the Nyong Series with a resource estimated at 82.9 Mt at 32.1% Fe and whose origin remains debatable. The mineralization occurs as NE-SW oriented discontinuous lenticular bodies of magnetite-bearing pyroxene-gneisses (MPG) hosted by ortho-derived gneisses. Rare amphibolites …

Magnetite (Fe 3 O 4) is a common iron ore mineral in iron ore deposits of metasedimentary and magmatic origin.Magnetite has an inverse spinel structure and is partly altered in near-surface environments to hematite (Waychunas, 1991) or kenomagnetite.Hematite is commonly thought to form from oxidation of magnetite in the …

The Pingchuan iron deposit, located in the Yanyuan region of Sichuan Province, SW China, has an ore reserve of 40 Mt with ~ 60 wt% Fe. Its genesis is still poorly understood. The Pingchuan iron deposit has a paragenetic sequence of an early Fe-oxide–Pyrite stage (I) and a late Fe-oxide–pyrrhotite stage (II). Stage I magnetite grains …

Magnetite and hydrogoethite account for 16.71–17.74 and 8.04–10.50% of the component, respectively; the proportion of iron distributed in gangue minerals and finely dispersed iron hydroxides is very insignificant. Thus, the main iron losses during magnetic separation are accounted for by hematite and hydrogoethite, which have a very low ...
Petrochemistry of Two Magnetite Bearing Systems in the Precambrian Belt of Southern Cameroon
Magnetite-(apatite) ore deposits are interpreted as being formed by the crystallization of iron-rich ultrabasic melts, dominantly generated by the interaction of silicate melts with oxidized P-F-SO4-bearing sedimentary rocks. This hypothesis is supported by geologic evidence, experimental studies, numerical modeling, stable and radiogenic …
