The tentative ascending order of process refractoriness of iron ores is massive hematite/magnetite < marine black iron oxide sands < laminated soft friable siliceous ore fines < massive banded magnetite quartzite < laminated soft friable clayey aluminous ore fines < massive banded hematite quartzite/jasper < massive clayey hydrated iron oxide
By studying moraines in the Vestfold Hills of east Antarctica we identified two types of magnetite quartzite banded iron formation BIF ; a light red hematite rich BIF and a light gray BIF The light red hematite rich BIF is mainly composed of magnetite hematite quartz limonite with small amounts of sericite and apatite
Five specific types for BIFs in the NCC can be divided on the basis of their occurrences in greenstone belts successions and their relations with rock assembly 1 amphibolites or hornblende plagioclase gneiss and magnetite quartzite association; 2

Banded magnetite quartzite BMQ ore occurs as separate veins in iron ore mines and recovered while mining the natural hematite ore In India such ores are considered as low grade iron ores with Fe content of 25 45% SiO 2 30 60% and Al 2 O 3 1 5% No commercial plant has been set up so far to recover the iron values from such ores for any industrial
this paper pinpoints the thermal energy storage performances of two TESM quartzite as classic thermal energy storage material commonly used in CSP and magnetite as emerged thermal energy storage
The magnetite quartzite was collected from Liaoning China The chemical composition analysis of raw material was listed in Table 1 From Table 1 the main chemical compositions of the ore are Fe and SiO 2 with the contents of % and %
The magnetite quartzite map unit RAqz; Lahondère et al 2003 forms dark resistant ridges of highly variable length with mapped outcrops nearly 70 km long This magnetite quartzite is typically closely associated with impure dolomitic marble that reach thicknesses of several tens of meters but is laterally impersistent The magnetite
Magnetite is xenoblastic and less frequently idioblastic and amoeboid Metamafic ultramafic rocks Metamorphic rocks of ultramafic to mafic compositions occur in the study area as floats and more rarely lenticular and elliptical bodies of metaperidotites metagabbros metapyroxenites and amphibolites spatially associated with iron
this paper pinpoints the thermal energy storage performances of two TESM quartzite as classic thermal energy storage material commonly used in CSP and magnetite as emerged thermal energy storage filler material The TES performances included charge discharge and cycle efficiencies utilization rate In the first place the developed numerical
