Expanded Metal Mesh: The Advantages of Wear-Resistant Screening in Australia’s Pilbara Iron Ore Mines
2026-04-28
Australia’s Pilbara iron ore contains high-hardness hematite. Expanded metal mesh, woven from ZGMn13 high-manganese steel with a mesh size of 0.2 mm, has a service life three times longer than traditional screen mesh in screening operations at Rio Tinto’s Super Pit, whilst improving screening efficiency by 28%. The diamond-shaped apertures are optimised for iron ore particles, achieving a fine powder recovery rate of 98% and saving AUD 20 million annually in screen mesh costs. Certified for wear resistance by the Australian Mining and Metals Association (AMMA), it has become a core component in the iron ore belt.
