Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron II and iron III.
Black iron oxide is used as a pigment and in polishing compounds, medicines and magnetic inks. Also see hematite. A primary ore of iron. Hematite is processed to produce iron which is used to make steel which, in turn, is used in everything from automobiles to flatware to the machinery used to make almost everything else we use.
Many different minerals can be combined with iron in producing steel. Another use for our natural mineral is for heat storage or as an iron source for iron catalysts. Our customers are using our natural iron oxide mineral because it can store heat very well. They are mixing our Magnetite for over 30 years in heat blocks in Night Storage Heaters. If you look for a larger storage opportunity for thermal heat , Magnetite is a sustainable solution. Facts about our natural mineral that confirm its potential for upscaling heat storage are clear:.
Do you want to prevent surface defect in the casted metals made in foundries? Then our product grades for foundry are your solution. We have this product available in several grades. LKAB Minerals mines and processes the natural mineral magnetite from which a very pure, dried and fine milled powder, is made. Owning the source and processing plant to make Magnetite ensures our customers with a long-term, reliable source of consistent quality material.
Our dried fine powdered iron oxide is ferri-magnetic, greyish-black in colour as well as thermally and electrically conductive. Today, geologists can study the magnetic properties of rocks of various age and reconstruct the history of change in Earth's magnetic field. This information is available for multiple locations on multiple continents. It can also be used to learn about plate tectonics and the movement of continents over time.
A similar orientation of tiny magnetite grains occurs in the settling of sediment particles, locking clues to Earth's magnetic history into some sedimentary rocks.
