“…Red mud can be used to produce ceramic water brick, [ 16 ] ceramic wall brick, [ 17 ] brick of pottery and porcelain granule materials. [ 18,19 ] RM has used as the main raw material, with fly ash, stone slag, developed a red mud baking‐free brick. Red mud is still a good plastic filler and heat stabilizer, for the filling of plastic products which can improve the anti‐aging properties [ 20 ] and can produce red mud/plastic flame retardant film and new plastic building materials.…”

Industrial waste red mud (RM) was filled in the chlorinated polyethylene rubber (CPE) to replace carbon black (CB) at various ratios, that is, RM/CB (40/20, 20/40, 10/50, 5/55, 0/60) in the production of CPE/RM composite materials. The mechanical and thermal properties of CPE/RM with varied proportion of RM and CB were studied. The tensile strength of the CPE/RM/CB composite were improved compare to without RM (ie, improved from 10 to 14 MPa) and thermal degradation temperature (T d2) has improved from 435 C to 445 C, when the content of red mud was 20 phr. After aging for 3 days, the hardness and tensile strength of CPE/RM/CB composites were improved, that is, increment in hardness by 10 shore A and tensile strength by 2 MPa. CPE shows good thermal stability (with T d2 = 445 C) with the increment of RM and CB proportion, noticeably, when the ratio of red mud/carbon black is 20/40. The analysis by RPA (Rubber Process Analyzer) showed Payne effect became apparent when the amount of red mud was more than 20 phr. The compound with 60 phr CB load showed the largest elastic modulus G 0 which decreased fastest at strain 0.28%, almost as the same as 40/20 CB/RM, but the elastic modulus G 0 of 40/20 CB/RM showed a slight decrease when the strain exceeded 65%. The overall properties of the composite filled with 20 phr red mud were better in comparison with other varied ratios. The developed composite can be used to manufacture plastic runway or rubber hose.

“…In Russia, the annual increase in alumina production waste is 7-8 million tons with a total volume of 600 million tons, which are concentrated in sludge storage mainly in the Sverdlovsk region (Ural region). Thus, red muds in the form of a significant amount of off-balance materials of alumina production can be considered as a source of the main charge material for producing cast iron and steel, while reducing the volume of mud storage areas can solve a major environmental problem in the production areas of aluminum enterprises [8,11,12].…”

“…Since iron in red muds is present in both oxide and hydroxide forms, it is of scientific and technical interest to carry out processing taking into account phase transitions in a reducing medium. Many studies on waste recycling are aimed at developing disposal methods taking into account the multicomponent composition for obtaining various functional materials [12], such as building materials [13][14][15], paints and pigments [16], catalysts [17], sorbents [18] or selectively isolated oxides of titanium, aluminum, silicon and iron [19][20][21]. The most promising and effective, as well as reasonable from the point of view of solving environmental problems, is the direct reduction of some metals from oxides [22][23][24].…”

The reduction kinetics of serial phase transitions of iron oxides during reduction to a metallized state with different modes of technical hydrogen supply has been studied and substantiated. The results of the pellets formation when 3-5 % molasses is added to the red mud as a binding reagent are presented. The dependences of the reduction rate of iron oxides on the hydrogen flow rate are obtained. Based on the results of the experiments, a kinetic model was constructed, and with the help of X-ray phase and spectral analysis, it was proved that the agglomerates formed after heat treatment received high strength due to the adhesion of reduced iron particles with red mud particles. The use of a new type of charge materials in melting units will reduce the amount of emissions and dust fractions, as well as increase the metal yield.
