• Malmberget Iron Ore Mine, Sweden

     · Processing All of the ore mined at Malmberget is crushed and screened and is then upgraded using magnetic separation technology. Concentrator output is then processed to give sinter fines, olivine pellets or concentrate for iron powder production. In 2004, LKAB announced a 350m investment in a third pelletising plant for Malmberget.
