Dry magnetic separation of high-sulfur fine coal was carried out using a novel permanent magnet high-gradient magnetic separator (HGMS). The samples were analyzed using a vibrating sample magnetometer (VSM) and X-ray diffractometer (XRD) to determine the properties of the different size fractions of pulverized coal. It was found that magnetic …

 — Fly ash, a substantial byproduct of coal combustion in thermal power plants, poses significant disposal challenges due to its vast generation and limited utilization. …

 — Coal fly ash was first mixed with water at a liquid-to-solid ratio of 4:1 (mL/g) and then placed into a wet magnetic separator. Magnetic flux densities of 4300 G and 10 800 G were applied. The magnetic component stuck to the induced magnetic balls when the fly ash solution flowed around the balls in the magnetic separator.

The concentrate produced will be directed onto the cleaner magnetic separator circuit, mixing once more with the liberated magnetite from the primary cyclone cluster, while the tailings will be discarded as final tails. Cleaner magnetic separator circuit . The cleaner magnetic separator circuit works in the same way as

 — Magnetic Separator can be either dry or wet. The magnetic separator can also be classified as permanent or electromagnet magnetic separator. Magnetic separator for mineral processing industry falls into three basic categories: low, medium and high intensity, based on the relative magnetic field strength employed to accomplish separation.

 — Dry permanent magnetic separators have been widely used in the mineral and coal processing industries due to their simple operation and high separation efficiency. These tools not only discard some amount of bulk gangue from the raw ore, thereby reducing the volume of the grinding operation and cutting energy consumption, but also …
