  • RRA Red Mud Flocculants Ecolab

    RRA Red Mud Flocculants Ecolab

    This red mud residue must be removed prior to further processing of the saturated solution to ultimately precipitate a purified alumina trihydrate product. Red mud removal requires the use of flocculants effective in bridging and entrapping fine red mud solids to rapidly separate … read more

  • Red Mud Settling Flocculants Extraction Of Aluminium

    Red Mud Settling Flocculants Extraction Of Aluminium

    Red Mud Settling Flocculants. SINOFLOC red mud setting flocculants is used for settling aluminum red mud slurries in alumina plants, which provide high settling rates, better separation performance and reducing suspended solids significantly. SINOFLOC products could improve the liquor filtration operations and make the processing more economical. read more

    Nuggets Production by Direct Reduction of High Iron Red Mud

    May 01, 2013 LUO Dacrcheng, LIU Jun-feng, YI Ping-gui, et al. New Process of Utilizing Red Mud From Alumina Treating Plant to Produce High Quality Direct-Reduction Iron [J]. China Mining Maga- zine, 2002, 11(5): 50 (in Chinese). [lo] GAO Jian-yang. Research on New Comprehensive Utilization Method for Red Mud From Bayer Process [D]. read more

  • Minerals Free Full Text Concentration of Rare Earth

    Minerals Free Full Text Concentration of Rare Earth

    One of the potential sources of rare-earth elements (REE) is the industrial waste known as red mud (bauxite residue), in which the majority of REE from the initial bauxite are concentrated via the Bayer process. Therefore, the studies of the subject, both in Russia and outside, focus almost exclusively on red mud processing. This article looks into the possibility of REE concentration into red ... read more

  • Concentration of Rare Earth Elements Sc Y La Ce Nd

    Concentration of Rare Earth Elements Sc Y La Ce Nd

    May 30, 2020 It should be noted that most studies of the separation of REE from alumina products have focused on the processing of red mud. In this article, we made an attempt to study the possibility of obtaining the REE concentrate from electrostatic precipitator (ESP) dust, which is an intermediate product of kiln sintering in alumina production. read more

  • CN103131854A Method for comprehensively recovering

    CN103131854A Method for comprehensively recovering

    The invention relates to a method for comprehensively recovering scandium and titanium by leaching red mud with titanium white waste acid, which comprises the following steps: at ordinary pressure, dipping red mud with titanium white waste acid having a liquid-to-solid ratio of 4.0-6.0, performing secondary acid dipping on the leached slag, dealkalizing the secondary acid dipping slag, … read more

  • Dealing with Red Mud By Product of the Bayer Process

    Dealing with Red Mud By Product of the Bayer Process

    Jul 08, 2003 If red mud is completely neutralised, 15-20 times the volume of sea water is required. This requires extensive and expensive pumping and although results in an inert product, it is completely worthless. However, Virotec has found that slightly less than complete neutralisation can be achieved with much less seawater. read more

  • Selective recovery of vanadium from red mud by leaching

    Selective recovery of vanadium from red mud by leaching

    Aug 01, 2021 Selective leaching of vanadium and separation of iron from red mud by using oxalic acid and sodium sulfite were put forward. The main influencing factors of selective leaching were studied and the leaching mechanism was analyzed with XRD, SEM-EDS, thermodynamic theory and leaching kinetics. read more

  • Bauxite Red Mud Disposal Thickening Filtering CCD

    Bauxite Red Mud Disposal Thickening Filtering CCD

    More importantly, the Orbite process can be used to treat existing red mud, extracting the residual alumina and other valuable metals in it, while completely eliminating the toxic elements. This technology presents an attractive opportunity for companies operating alumina extraction plants, and for governments of regions with red mud deposits ... read more

  • Aluminum Mineral Processing and Metallurgy Iron Rich

    Aluminum Mineral Processing and Metallurgy Iron Rich

    Nov 05, 2018 Bauxite is the main source for alumina production. With the rapid development of iron and steel industry and aluminum industry, high-quality iron ore and bauxite resources become increasingly tense. However, a lot of iron-rich bauxite and Bayer red mud resources have not been timely and effectively recycled, resulting in serious problems of environmental pollution and wastage of resources. read more

  • Red Mud Processing Enervoxa

    Red Mud Processing Enervoxa

    Recycling and processing red mud are more cost-effective than storage at red mud dumps. Given the prospective increase in environmental payments and fines for the use of red mud dumps and the deficit of free land in the city near existing facilities that processing aluminum bauxites , the processing of red mud is becoming increasingly more ... read more

  • Hydrometallurgical Recycling of Red Mud to Produce

    Hydrometallurgical Recycling of Red Mud to Produce

    Aug 02, 2021 Red mud is a polymetallic waste generated during Bayer's process of alumina production. High alkalinity (pH 11), multiple elements, and micron-sized particles make red mud recycling energy-intensive and challenging. The following work presents a hydrometallurgical flowsheet for separation of different red mud elements and recovery of high purity Fe (II) product using cost … read more
