Magnetic separation of coal fly ash from Bulgarian power ...

2020-10-1  Fly ash from three coal-burning power plants in Bulgaria: 'Maritza 3', 'Republika' and 'Rousse East' were subjected to wet low-intensity magnetic separation. The tests were performed at different combinations of magnetic field intensity, flow velocity and diameter of matrix elements. It was found th

Fine Coal Desulfurization by Magnetic Separation and the ...

2014-12-31  Pyrite in fine coal was heated selectively by microwave energy to strengthen its magnetism in this study. Then, the inorganic sulfur in fine coal (−0.5 mm) was removed using a 2 T strong magnetic roller magnetic separator. The migrating regulation of organic sulfur-containing groups and harmful elements was analyzed by employing a microwave energy-intensive process.

Sequential particle-size and magnetic separation for ...

2020-2-1  The enrichment factor and REY recovery in the magnetic separation step were 1.12 and 91.64 %, respectively. Overall REY recovery for the sequential separation process was 71.21 %, with an overall enrichment factor of 1.23. Sieving followed by magnetic separation effectively decreased the Fe 2 O 3 and CaO contents of this fly ash.

One-step preparation of environment-oriented magnetic

2021-3-1  In this work, we report the preparation of magnetic coal-based activated carbon (MCAC) with high adsorption performance, with Ningxia coking coal and ferrocene as the raw materials. Coal-based carbon was directly activated with KOH at 1000 °C, whereas metal particles were attached its surface through an in-situ process. As a result, MCAC has a ...
