·La magntite est un minral naturel qui est l un des plus courants fonte minerais et est largement distribu dans le monde entier C est un minral noir d aspect mtallique dot d une proprit magntique distinctive d où son nom La magntite a la formule chimique Fe3O4 ce qui signifie qu elle est compose de deux ions fer Fe combins à trois ions oxygène O
·The magnetite series and ilmenite series granitic rocks Mining Geol Japan 1977; 27 293 305 [2] Ishihara S Matsuhisa Y Oxygen isotope constraints on the genesis of the Miocene Outer Zone Granitoids in Japan Lithos 1999; 46 523 534 [3] Ishihara S The redox state of granitoids relative to tectonic setting and earth history The magnetite
The formerly untapped tailings still contain financially profitable quantities of ore minerals magnetite ilmenite and pyrite The size of the tailings pond is approximately 145 hectares and is located about two kilometres to the north of the Otanmäki community Thus at the above mentioned recovery rate Otanmäki Mine s yearly
·Subhedral ilmenite crystals showing strong bireflectance from medium to very dark grey are surrounded by heavily weathered magnetite light grey containing lamellae and irregular patches of
·In the ilmenite‐series granitoids the Cl contents are mostly below the detection limit varying from % to % in the ilmenite series except for the sample 6910104 % Cl which occurs in the Sanyo Belt but belongs to the local magnetite series having low magnetite content shown by the magnetic susceptibility of 284 x 10 ‐6 emu/g
·The Quaternary stream sediments of the Diit area southern Red Sea coast Egypt were mineralogically studied for their content of economic heavy minerals The study area covered approximately 450 km2 and included three main parts Wadi and Delta Diit as well as Diit lens The mineralogical investigation revealed that these sediments contain considerable
·Ilmenite pyriboles and magnetite dominate in THM of around 10 to 15% The width of the sand bodies is large and ranges from 500 m to over 4000 m with thickness of around 12m
·Magnetite and ilmenite are two common minerals in igneous metamorphic and sedimentary rocks In particular they are major ore minerals in many hydrothermal iron deposits banded iron formation and magmatic Fe Ti V and Fe Ti P ore deposits Dupuis and Beaudoin 2011 Dare et al 2014 Nadoll et al 2014 Recently a number of studies focus on trace
The small ilmenite magnetite gabbros 1881 Ma at Koivusaarenneva Kaireneva Peräneva Lylyneva and Riutta make up a chain of igneous bodies in tonalite in the northwestern part of the Central Finland Granitoid Complex Fig Kärkkäinen and Bornhorst 2003; Sarapää et al 2001 Gravity and magnetic highs and anomalies in Electromagnetic EM measurements
