Magnetic Separation and Recycling of Goethite and
In this study, magnetic separation was applied to separating goethite from calcium sulfate with maghemite (γFe 2 O 3) fine particles as the carrier, which were prepared by roasting −1 μm pure magnetite mineral particles The SEM images and XRD patterns indicated the precipitation of goethite on maghemite fine particles in the goethite process, which made the goethite aggregates magnetic, while To solve the filtration problem, magnetic seeding and separation were applied to improve the goethite process And the experiment proved that the iron precipitated on the surface of the magnetic seeds to form a coreshell structure and the magnetic core endowed the particles magnetismMagnetic separation of iron precipitate from nickel Altiner, M Roasting of a LowGrade Goethite Ore Using Horse Residue and Its Beneficiation by Magnetic Separation Mining, Metallurgy Exploration 37, 1357–1365 (2020) /101007/s42461020002425 Download citation Received: 06 November 2019 Accepted: 19 May 2020 Published: 03 June 2020 Issue Date: August 2020Roasting of a LowGrade Goethite Ore Using Horse

The rock magnetic tests are a much more sensitive basis for recognizing the presence of goethite in natural samples than are XRD analyses The results suggest that goethite's contribution to the rock magnetic properties of soil and sediment samples may often have been underestimatedHigh Gradient Magnetic Separation of Iron Oxides and other Magnetic Minerals from Soil Clays Larger particles are captured more efficiently because of their greater overall magnetic attraction Goethite, hematite, lepidocrocite, and anatase are concentrated in the magnetic fraction, while quartz is concentrated in the tailings High Gradient Magnetic Separation of Iron Oxides Weak magnetic separation shows that under the magnetic field of 200 kA/m, goethite ores roasted by 15% of pine sawdust could achieve TFe 6164% with the recovery of 7975%, TFe 6175% with the recovery of 8016% for roasting with rice husk, and TFe 6147Biomass Roasting Reduction of Goethite Ores《矿物学报
