In a West African context this material is typically called Saprolite; in the Brazilian context this is Itabirite, and the Brazilian industry has very successfully developed flowsheets for this material using combinations of gravity separation, magnetic separation and flotation.
The Mbalam‐Nabeba Iron Ore Project is being developed by Sundance Resources, Cam Iron and Congo Iron in partnership with the Governments of Cameroon and the Republic of Congo.

An Itabirite is a laminated, metamorphosed, oxidefacies Iron Formation named for a rich Iron deposit in Itabira, Brazil. Additionally, the small tag on the specimen has the number R8656, which corresponds to the 'Geologisch Instituut Universiteit Van Amsterdam' label.
Hematite and Itabirite Sundance Resources . Hematite and Itabirite Worldclass iron ore resource What is hematite? Hematite is a black, grey or reddishcoloured mineral which is mined as the main source of iron. BRAZILIAN IRON FORMATIONS AND THEIR
itabirite beneficiation panafricanleadershipfoundation Beneficiation of the itabirite resource at Mbarga will utilise conventional Beneficiation Of Hematite Vs Magnetite is a leading global manufacturer of Iron Ore Beneficiation SRK News Iron ores come in come in many shapes and sizes (and mineralogies), so there is no one size fits all approach to beneficiation.
Bulkrock chemical analyses of auriferous (jacutinga) veins indicate enrichment in Au, Pd, Fe, Mn, Ba, Hg and Cr compared to fresh, nonaltered itabirite. Itabira is a worldclass iron ore district. Like Gongo Soco, auriferous veins truncate the foliated host rock (itabirite) and, consequently, a late to postBrasiliano age is inferred.

1995). The mineral assemblage indicates temperatures ranging from 300°C in the west region to 600°C in the east (Pires, 1995). 3. Mineralogy and petrography The analyzed ironrich rocks are comprised of hematitite and itabirite (Fig. 2). The difference between them is the proportion of iron oxide to quartz. The mineral composition of both sample
