Edison and Ore Refining Engineering and Technology
Edison planned to process 1200 tons of iron ore every twenty hours. The plant had three magnetic separators that could produce a total of 530 tons of refined ore. There was other equipment to re-refine what was left over to extract even more ore. But technical problems persisted. Iron ore rock crushers used in Edison's iron ore refining Magnetic Separators can be applied in mainly three ways: 1. Magnetic Separators for concentration or purification; Magnetic Separator can be applied in ore processing for separating magnetic materials, particular Iron. The advent of magnetic separation found favour in mineral processing for over 200 years ago. 2.How Does a Magnetic Separator Work GTEK Magnet

Why is iron magnetic? Physics Today AIP Publishing
Why is iron magnetic? The long‐sought explanation of the origin of ferromagnetism, which involves interactions both among the bound electrons and between bound and itinerant electrons, will guide the search for new magnetic alloys. The unravelling of the origin of magnetism in iron, cobalt, nickel and their alloys has been a fascinatingIron is a commonly known metal that has many useful properties. One of its most notable characteristics is its magnetic nature. Iron is indeed magnetic, meaning it can be attracted to magnets and can also be magnetized itself. This property is due to the arrangement of its atoms, which allows iron to create a magnet ic field.Is Iron Magnetic? 13 Facts You Should Know! Lambda Geeks

Comminution and classification technologies of iron ore
Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.Multotec supplies a complete range of magnetic separation equipment that effectively separates ferromagnetic and paramagnetic particles from dry solids or slurries. Magnetic separators are renowned for their separation of magnetic ore; they can also serve as an electromagnet effective for removing tramp metals, providing the ideal solutionMagnetic Separators Multotec
