Dec 10 2015Iron sand in creeks is generally Magnetite from the weathering of igneous and metamorphic rocks and can be found a lot of places you would not expect it due to the glaciation of much of North America Magnetite is considered a high grade iron ore and is what is used in the traditional tatara furnace to make tamahagane for Japanese swords
china process of iron ore magnetite For iron ore mining process or iron ore processing plant is a reletively simple separation process that concentrate iron content from the iron ores as there are seveal different types of iron ore so the iorn ore mining process is not all the same for example there are magnetite iron ore hematite iron ore and
Iron ore is a mineral substance which when heated in the presence of a reductant will yield metallic iron (Fe) The iron ore usually very rich in iron oxides (Fe3O4 and Fe2O3) Iron ores are mostly dark grey to rusty red in color and high specific gravity Two main types of iron ore used for iron making – Magnetite (Fe3O4) and Hematite
The paragenesis textures and chemical compositions of magnetite in two mafic to intermediate intrusions and four IOA deposits in SE Missouri were studied to discriminate between igneous and hydrothermal sources In this study we found that replacement magnetite with mineral inclusion-rich cores yields erroneously high Ti Al Si Mg and Mn contents as determined by EMP and LA-ICP-MS
