Magnetic separation: its application in mining, waste
The use of strong magnetic field gradients and high magnetic fields generated by permanent magnets or superconducting coils has found applications in many fields such as mining, solid state chemistry, biochemistry and medical research Lab scale or industrial implementations involve separation The non magnetic particles are moved down to the lower hopper following the gap of the lower magnetic pole and the magnetic separation of magnetic minerals is completed At this point the pulsating box is activated causing the pulp shaking up and down in order to remove impurities and improving the concentration of the pulpMagnetic separation for mining industry – Magnetense Magnetic separation is most commonly used in the mining industry to separate “tramp ore,” or unwanted waste metals, from the rest of the bulk material Tramp ore typically consists of the manmade byproducts created by the mining process itself, such as wires from explosive charges, nuts and bolts, nails, broken pieces from hand tools such Magnetic Separation in the Mining Industry
