Extraction of Iron, Iron Mining, Iron Ore Processing

Siderite Iron Ore Processing Like limonite, siderite is a low-grade iron ore that is unstable. The iron ore processing technology used in siderite concentrator are gravity separation and strong magnetic separation. Different siderite has different iron ore processing methods. The extraction of iron from single siderite with coarse grain size is suitable to be treated with single gravity separation, single strong magnetic separation and combined process including two kinds of iron ore processing technologies.

Magnetic Elutriation Technology for Clean and Efficient ...

2013-9-20  Magnetic elutriation improves the quality of low-grade domestic iron ore by using analternating-current, pulsed-magnetic field to clean iron ore into a highly refined product. This innovative process differs from conventional drum type magnetic separation systems by using permanent magnets that cause magnetic entrapment.Drum separators use a less effective, static magnetic field and entrap weakly-magneticparticles, known as middlings, which ultimately contaminate the iron product.The 5R Research technology is a true continuous-counter-current design with a uniform but dynamic magnetic field throughout the system. As crude iron ore entersthesystem, gravity pulls the magnetically gatherediron ore particle strings downward.Only rich iron particles move downwards, while tailings particles move upwards. Theselective downward movement of the product is assisted by powerful electromagnetsthat agitate and hold the strongly magnetic ore preventing it from being flushed out of the system. Then, water flushes the weakly magnetic middlings and sandy tailingsout of the system. Highly refined iron ore
