Iron phosphate mediated magnetite synthesis: a

Introduction Magnetite (Fe 2+ Fe 2 3+ O 4), a magnetic mineral found in both geological and biomineralization contexts, has magnetic and biocompatible properties that allow for a wide range of applications 1–3 In addition to igneous rocks, magnetite also occurs in sedimentary rocks, including banded iron formations and in lake and marine sediments as both detrital grains and as magnetofossils Magnetite nanoparticles are also thought to form in soils, where they probably oxidize rapidly to maghemite The chemical composition of magnetite is Fe (Fe )2(O )4 This indicates that magnetite containMagnetite

Rogetta iron ore project one of the biggest iron ore

It is expected to produce one million tonnes (Mt) of magnetite iron ore concentrates a year, over its estimated mine life of eight years, starting from 2020 The average mining capacity of the project will be 6,600t of ore The mine continuously produced 30,000 tonnes per day (tpd) by May 2005, marking as one of the world’s fastest rampups to full production Since it began operations, Palabora has created a Palabora Copper Mine, Palabora, South Africa Mining
