About this site
Itabirite, also known as banded-quartz hematite and hematite schist, is a laminated, metamorphosed oxide-facies iron formation in which the original chert or jasper bands have been recrystallized into megascopically distinguishable grains of quartz and the iron is present as thin layers of hematite, magnetite, or martite (pseudomorphs of hematite after magnetite).
About this site
Definition of itabirite A laminated, metamorphosed oxide-facies iron formation in which (1) the original chert or jasper bands have been recrystallized into megascopically distinguishable grains of quartz and (2) the iron is present as thin layers of hematite, magnetite, or martite (Dorr & Barbosa, 1963).
About this site
Itabirite mineralisation is a metamorphosed iron formation composed of iron oxides (hematite, magnetite, martite), abundant quartz, very rarely mica and other accessory minerals. Brazil’s itabirite deposits range in scale from 1 to 4 billion tonnes, with average grades of between 37% Fe and 52% Fe. The mineralisation is beneficiated to
About this site
Mar 01, 2020 The occurrence of P-bearing minerals in itabirite and iron ore in the QF has long been mentioned in the literature (e.g. Barbour, 1973, Morgan et al., 2013, Spier et al., 2007). Apatite is the major P-bearing mineral in unweathered itabirite, occurring as a trace mineral (Morgan et al., 2013, Spier et al., 2007).
About this site
This paper presents a mineral liberation study on two iron ore samples from the Quadrilátero Ferrífero, in Brazil: compact itabirite of low-grade metamorphism (CI) and friable itabirite of high
