Determine the empirical formula of magnetite which contains 72.4% Fe 55.85 and the rest oxygen 16.00 ?
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 oxide nanoparticles synthesized by the wet
chemistry Is used to determine concentrate analysis. These lab results are summarized on liberation-grind curves. Ore parameters are then fed into a computer where a weighted average scheme fits the data into a bench block format. A single value for each parameter can then be assigned to each ore block. The blocks measuring 100 feet by 300
Magnetite is very easy to identify. It is one of just a few minerals that are attracted to a common magnet. It is a black opaque submetallic to metallic mineral with a Mohs hardness between 5 and 6.5. It is often found in the form of isometric crystals.
Taking the highest V value and assuming that all V is hosted in magnetite gives a V content in magnetite of 0.2 %. Using this ratio the Fe in magnetite can be estimated. The estimated amount of Fe in magnetite by both methods was subtracted from the total Fe reported by Minalyzer CS.
Magnetite is a rock mineral and one of the main iron ores with the chemical formula Fe 3 O 4.It is one of the oxides of iron and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite called lodestone will attract small pieces
Magnetite is an important ore of iron. Well formed crystals are popular among mineral collectors and the magnetic Lodestone variety is frequently sold in hobby shops to amateur collectors. Magnetite is also of significant interest to the science community due to its strong magnetic properties.
Magnetite weighs 5.17 gram per cubic centimeter or 5 170 kilogram per cubic meter i.e. density of magnetite is equal to 5 170 kg/m³. In Imperial or US customary measurement system the density is equal to 322.753 pound per cubic foot lb/ft³ or 2.99 ounce per cubic inch oz/inch³ .
