Magnetite is an iron ore/iron oxide. Not all iron ore/iron oxide is magnetite. These are terms used for a group of minerals where magnetite is one of them. MagnaDense is manufactured from the mineral magnetite. We mine large lumps of Magnetite (Iron oxide) from our mines in northern Sweden. We produce MagnaDense in specific sizes that fit the different industries we supply. LKAB, our mother company, manufactures and delivers upgraded iron ore products and services for iron manufacturing.
