Feb 01, the disposal of bayer red mud tailings now seriously threats the environment safety. reduction and recycling of red mud is now an urgent work in aluminum industry. high gradient superconducting magnetic separation (hgsms) system was applied to separate the extreme fine rm particles ( 100 μm) into high iron content part and low iron content.

Feb 13, recovery of alumina from magnetic separation tailings of red mud has been investigated by na2co3 solution leaching. x-ray diffraction (xrd) results show that most of the alumina is present as 12cao 7al2o3 and cao al2o3 in the magnetic separation tailings. the shrinking core model was employed to describe the leaching kinetics. the results show that the calculated activation.

Feldspar is a common raw material used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. feldspar is ground to about 20 mesh for glassmaking and to 200 mesh or finer for most ceramic and filler.

Jaimeson et al. () conducted a magnetic separation investigation on darling range red sand using a combination of low intensity magnetic separator (lims) and wet high intensity magnetic separator (whims). the results reported ~56% as fe203 to the magnetic fraction and a relatively clean non-magnetic fraction composed of 4%.

Jan 03, iron and aluminum in red mud were recovered by a reductive sintering–magnetic separation–digesting process. the raw materials were composed of ordinary bayer red mud, mgo, na 2 co 3 and c, in which mgo and na 2 co 3 were used as mineralizing agents, and c as a reductive agent. sintering orthogonal experiments showed that 55.03% content of iron concentrate with 91.02% iron recovery.

Jan 15, recovery of iron from bayer red mud was carried out by direct reduction roasting–magnetic separation process. moreover, the residues after magnetic separation process were reused as building materials. this combination recycling process showed the potential benefits of zero-emission of red mud wastes from the production industry of.

Jan 15, red mud is a solid waste produced in the process of alumina extraction from bauxite. in this paper, recovery iron from bayer red mud was studied with direct reduction roasting process followed by magnetic separation, and then building materials were prepared from alumosilicate.

Key words: red mud, microwave, carbon heat reduction, magnetic separation introduction red mud is the polluting waste residue of alumina plant when producing alumina. according to the differ-ence between technics and technological level of alu-mina production, the average yield of 1 ton of alumina is produced with 1,0 ~ 2,0 tons of red mud.
