Although red iron oxide (rust) the most popular metallic oxide used for getting a thermite reaction, magnetite can also be used to replace red iron oxide. Due to its unique properties, magnetite is a mineral of great scientific interest and it is widely used in laboratories as …Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron(II) and iron(III). Its empirical formula is Fe 3 O 4, and it is often expressed as iron(II,III) oxide. In the past, it has been called ferrous–ferric oxide and triiron tetraoxide. Magnetite is found in igneous, metamorphic, and sedimentary rocks.

The synthesis of magnetite NPs is usually provided by alkaline coprecipitation of iron ions Fe 2+ and Fe 3+ in the ratio 1:2. Fe 2 + + 2 Fe 3 + + 8 OH − = Fe 3 O 4 + 4 H 2 O The changes in the molar ratio influence the composition of the products, the size of magnetite NPs, and their magnetic properties ( Iida et al., 2007 ).magnetic iron sand is alternately arranged with charcoal in a small blast furnace called ' Kaku-ro ', and refined by deoxidization at a relatively low temperature in a warm blast introduced from the tuyere, yields a white pig iron of extremely high quality known as charcoal pig iron.

Magnetite is a type of iron oxide that is naturally occurring, and it is what makes black sand magnetic. This type of sand can be found on many beaches in Hawaii, like Punaluu. But they are other places in the world that have black sand beaches. For example, New Zealand and Iceland have impressive stretches of black sands.Introduction Magnetite, also known as magnetite black sand, is a form of iron oxide. It is a very stable and dense material, and is widely found in nature across the world in a variety of natural settings as a commonplace mineral; it most commonly occurs in nature in a granular form as a sand or grit.

Magnetite is an ore of the oxide mineral magnetite. Is an equiaxed crystal system. The crystals are octahedron and dodecahedron. The crystal face has stripes. Mostly granular aggregates.
