    摘要： A method of recovering magnetite from bauxite residue, comprising reducing the pH of the bauxite residue to form a treated bauxite residue, drying the treated bauxite residue, adding to and mixing into the treated bauxite residue a solid source of carbon, to create a mixture, heating the mixture to a reduction temperature of at least 800° C. in a reducing reactor to produce a reduced bauxite residue in which a major portion of Fe2O3 present in the treated bauxite residue has been converted to Fe3O4, exposing the reduced bauxite residue to a particle separation step, and then separating the reduced bauxite residue into an iron-enriched portion and an iron-depleted portion.

    摘要： A method of effectively extracting metal ions by sonication from red med that is waste remaining after extracting aluminum from bauxite. The method includes: (a) introducing, into a reactor placed in a constant-temperature tank, (1) a neutralized red mud slurry and an acidic solution or (2) red mud slurry, distilled water and an acidic solution, to form a red mud slurry, and heating the constant-temperature tank to allow the red mud slurry to react while sonicating the red mud slurry, thereby extracting metal ions from the red mud; and (b) filtering a product resulting from step (a) to provide a filtrate and a red mud residue, and separating and recovering the filtrate and the red mud residue, wherein the sonication in step (a) is performed using an ultrasonic generator by applying ultrasonic waves to an ultrasonic tip placed in the constant-temperature tank.
