Abstract. The world's steel industry contributes 7–9% of global greenhouse gas emissions. This is principally from blast furnaces, basic oxygen steelmaking, sintering and pelletising. The push to reduce carbon emissions will see a change, where green high-grade magnetite with ≥68% Fe grade becomes the preferred feedstock for the steel ...

Magnetite is an iron mineral, specifically, it's an oxidized form of a balanced blend of iron ions. It contains both divalent (Fe²+) ions and trivalent (Fe³+) ions. It's most commonly seen as octahedral crystals with a black color, although some may take on a brownish tinge. Being a relatively simple mineral, simply an oxidized form of ...

The origin of magnetite-(apatite) iron deposits (MtAp) is one of the most contentious issues in ore geology with competing models that range from hydrothermal to magmatic processes. Here we report melt inclusions trapped in plagioclase phenocrysts in andesite hosting the MtAp mineralization at El Laco, Chile. The results of our study …

The synthesis of iron oxide nanoparticles with control over size and shape has long been an area of research, with iron oleate being arguably the most successful precursor. Issues with reproducibility and versatility in iron oleate-based syntheses remain, however, in large part due to the mutable nature of its structure and stoichiometry. In this work, we …

Magnetite or black sand mining is supposed to be banned in the Philippines, but Moncano explained that the extraction of the said mineral offshore is allowed. He said, "Mining in shoreline is prohibited but offshore mining is allowed. If it is at least 1,500 meters from the shoreline going out to the sea, it is allowed.".

The formation of magnetite during the bioreduction of iron oxides is thought to be the result of topotactic reactions between aqueous ferrous iron Fe 2+ and the sites of structural ferric iron Fe ...
