  • Magnetism - Wikipedia

    Magnetism was first discovered in the ancient world, when people noticed that lodestones, naturally magnetized pieces of the mineral magnetite, could attract iron. The word magnet comes from the Greek term μαγνῆτις λίθος magnētis lithos, "the Magnesian stone, lodestone." In ancient Greece, Aristotle attributed the first of what could be called a scientific discussion of

  • Magnetic Separation Method - Mineral

    Magnetic Separation is the process, in which the "magnetically caused material is detached easily" by using a magnetic force. From last many years, magnetic separators are used for various separation process in recycling industry like Glass recycling, Scrap material, Pet flakes, Plastic recycling, Rubber recycling, Municipal solid waste (MSW), e-waste recycling etc.

  • ChemTeam: Separation of Mixtures

    I. Hand Separation. An example which could be separated by hand might be a dry mixture of salt and sand. Manually picking out the sand does not change the chemical identity of the salt or the sand. Even though this technique is crude, it does show up in making an important discovery. It was the discovery of optical isomers by Louis Pasteur in 1844, the first major discovery of his scientific

  • Magnetic separation - Wikipedia

    Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those that are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are
