Hematite's straightforward iron and oxygen recipe gives it one kind of behavior, while magnetite's mix of ferrous and ferric iron creates different magnetic properties. Though both are iron oxides, this subtle difference in chemistry leads to distinct appearances, behaviors, and uses for each mineral.

Hancock Prospecting, through wholly owned subsidiary Atlas Iron, is pushing ahead with approvals for Ridley, which could eventually produce 16.5 million tonnes of magnetite a year.
Magnetite is a raw material, of which the item form is found abundantly in the Mountains and Mountains Caves, as well as within the Jellyshroom Cave and Lost River. Magnetite can also be found as a large resource deposit. Magnetite was at one point renamed to Iron Ore, but was changed back to Magnetite shortly afterward. In real life, Magnetite is …
magnetite, iron oxide mineral (FeFe 2 O 4, or Fe 3 O 4) that is the chief member of one of the series of the spinel (q.v.) group.Minerals in this series form black to brownish, metallic, moderately hard octahedrons and masses in igneous and metamorphic rocks and in granite pegmatites, stony meteorites, and high-temperature sulfide veins. …
Iron oxide nanoparticles are available in two common phases, namely magnetite (Fe3O4) and maghemite (Fe2O3). Upon exposure to oxygen atoms, the magnetite phase readily oxidizes into the maghemite phase with the partial conversion of ferrous ions into ferric ions. We report on the approach to determine the ratio of magnetite and maghemite in iron …
Flotation separation (direct or reverse) followed by de-sliming and magnetic separation is the most important beneficiation technique for upgrading feldspar.

In this study, we show that enrichment of Nb and Zr can occur in magnetite on the mineral scale formed by hydrothermal fluids at medium-to-lower temperature in a …
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 ...
Ancient people observed how lodestone, a magnetized piece of magnetite, attracted iron fragments, leading to the discovery of magnetism. In nature, you can find magnetite in its black, gray, and …
Eco-efficient and cost-effective process design for magnetite iron ore . Currently, the mining industry is facing several issues related to energy consumption so the optimized use of energy is an ever-increasing need. Mining – and especially minerals processing – routes for different ores (base metals, iron ore, bauxite, platinum, etc ...
Magnetite (Fe 3 O 4) is a key economically valuable component in iron ore and is extracted by dissolution processes, but among the Fe (oxyhydr)oxides its solubility behavior is one of the least understood.The objective of this study was to improve understanding of magnetite dissolution mechanisms leading to thermodynamic …
Mixed-valent iron [Fe(II)-Fe(III)] minerals such as magnetite and green rust have received a significant amount of attention over recent decades, especially in the environmental sciences. These mineral phases are intrinsic and essential parts of biogeochemical cycling of metals and organic carbon and play an important role …
Magnetic carrier flotation based on iron oxide nanoparticles can pave the way to promising new recycling processes for microplastic wastes.
The use of magnetite-based iron ore fines by means of fluidized bed technology has become a promising route to produce direct reduced iron. The significant influence of a prior oxidation treatment, which occurs in the preheating stage, on the subsequent fluidization and reduction behavior was observed in our previous study. As a …
Magnetite is mined at the Xstrata Copper Ernest Henry Mining operations in the north west of Queensland. The orebody is an iron oxide- copper- gold deposit with magnetite being the form of iron ore. In the past, magnetite was traditionally discarded as tailings at the mine site. However new
By far, the two most economically important iron ores are hematite and magnetite. Although hematite is more abundant than magnetite, magnetite has the higher iron content, so magnetite iron ore deposits are highly sought after. Economic magnetite deposits primarily occur in layered igneous rocks that formed from the slow cooling of …
